Logitech M570 Wireless Trackball Mouse - Ergonomic Design with Precision Tracking | Perfect for Office Work, Graphic Design & CAD Professionals

This review is intentionally being copied to both of my recent Logitech purchases to better highlight the distinct personalities of the equipment described. First of all... I use a trackball because of loss of manual dexterity. Long ago, I replaced my first trackball (Kensington) with the old Logitech model with the ball in the palm position as at the time that was a pretty good arrangement for me. The larger ball of the Kensington had become unmanageable for me, and I still had enough use of my hands that the configuration with the smaller ball was all the adjustment Ic required... It was back in the days when people still looked at you funny and asked what a trackball was... Anyway, I think Logitech still makes them, but it's no longer the correct solution for me... The squeezing or grasping action required for that configuration now irritated my muscles causing bad spasms... But I will mention that those trackballs worked pretty well. I did have three or four and came to notice that they weren't really made to last forever... Not that anything is... Sooner or later the sensors fail and that's that. Anyway, moving forward... My health has become more dicey. I now have considerably less control of, and sensation in my hands, so I was attracted to the M570 because of the finger grooves. They certainly do help me keep my hand where it needs to be. But the angle does not work and its tiresome for my failing muscles... and that ball is extremely difficult to control. Not a defect of the equipment, but a malfunction of my hand, and more precisely in this case, my thumb... The trackball is delightfully very responsive. But for me it's too fast and slick (!), even when adjusted by software. I did not return that trackball. It was not very cost effective to do so. It was not a free return... And who knows... Maybe a miracle will happen and I'll get stem cell therapy and get to use my body normally again. Ok. Maybe not. There was some reason I liked it... There was something v about it I wanted to keep... But it took awhile to figure it out... In the meantime, I upgraded to the Ergo... It's got a throttle (precision mode) that's good for keeping my tremors from destroying my hard work. And... It's highly programmable... I love that part... Now, normally (once upon a time in some other life I had) a trackball with this much initial resistance would have been of no interest to me. But that's a feature for me now... and it works to solve my accessibility issues just in its normal mode... And if I'm having a super tremendous awful day with bad tremors, I can turn on precision mode instead of getting extremely frustrated that I have to stop what I'm doing. Also... I love the ability to change the angle of rotation of my arm so that it's actually comfortable. This trackball was engineered with those types of issues in mind. But... They forgot the wonderful finger grooves that are on the much cheaper M570 model. For the price... I would have been very happy if that feature was also part of the Ergo. Like I said... I actually couldn't decide for quite some time why I wasn't sure which trackball to go with. I finally realized that those grooves were a really important feature that I didn't want to give up, as they help keep my fingers securely in place... Unfortunately, I do have to reposition my hand on the Ergo rather frequently because my hand doesn't know where it is, like it does on the M570... In the end, I had to keep the Ergo, because it's so controllable _for me_. I just wish it had the added benefit of helping me keep my fingers placed properly. The repositioning makes me concerned that It will get dropped or be the accidentally casualty of a bad tremor day. But, if so, I have the less sedate M570 to get me through until repair or replacement happens, right? So, the Ergo might not be your cup of tea if you don't need equipment you can really throttle down. It's not going to be about speed with this device, but that resistance is what I need. And to say that is not to say it isn't smooth in its operation. This is a turtle, not a hare! The turtle is what's going to win the race for me... I really wish Logitech would marry the best features of these two devices and send me one as soon as they do!!!I haven't gotten a chance to connect this mouse because it's not Bluetooth. There are some Q&A inferring that this mouse IS Bluetooth, but it is NOT. So if this is important to you, hopefully this clarifies. I had to buy a USB to USC adaptor because my brain could not handle searching for a new mouse.My only other complaint is that this mouse feels like it's made from cheap plastic. I'm coming off a magic mouse that feels way more expensive than this mouse. At $85, it's not a cheap mouse so it would be nice if it felt like I paid $85 for it.Having said all that, I did buy the adaptor. I hope this mouse works out.Update: I am returning it. I bought an upright mouse and I instantly took to it. I keep wanting to move this mouse with my hand, instead of just my thumb. My other mouse was half the price, packaging was nicer, and the mouse feels more expensive in my hands (not like a toy) - overall, just a better user experience.This is the third one I have purchased. I didn't buy this because my old ones died, this was purchased due to the fact they don't make this model anymore. Once the others die I'll have a replacement. This particular model (M570) has lasted nearly 10 years of heavy usage. I'm not sure about the new models but I'm convinced they made this one so well that Logitech didn't make any money off of it because no one replaced it with another due to breakage.To put it in perspective, as a photographer by trade I have processed over an estimated 36,000 pictures over the last 5 years using the same trackball. What impresses me is, this is the same trackball I used as an IT professional for 4 years earlier at my office.This device takes minimal maintenance, every once in a while you'll need to remove the ball (easy to do) and clean the human finger grease (it's gross I know) from the support pins that hold the ball in place.The one AA battery lasts about a year for me. I just hope Logitech continues this kind of quality in their future models.Great!I got this trackball mouse to use with my laptop in bed at night. It is a gaming laptop, so I tried using the mouse for FPS games, and (without training,) it is next to useless for that application. I have been able to utilize it for exploration, walking sim, and other non-twitch games, and it works reasonably well with those.It is a godsend for interacting with the web interface of my employer. I have to fill out radial menu and check box forms for a living, and it works very well for that.The wireless receiver can be daisy chained through a USB hub, freeing up my other USB ports for peripherals like gamepads and storage devices. I currently have it plugged into the second USB port on my cooling pad, which I power using one of the free USB-C ports on my laptop. I was a little surprised this configuration worked, but it does, so I use it.This trackball is not perfect for me, however. It is very precise, perhaps too precise for level of ability. I am disabled and have essential tremor. I cannot hold my hand still, even when resting on the device. This means that as my thumb manipulates the trackball, it kind of jerks around the screen a little. I have turned the mouse sensitivity all the way down, and it is usable, but it would be nice if there was a way to lower the sensitivity even more. Mouse acceleration is nice for getting around the screen quickly, but I am not able to utilize it because even on the lowest sensitivity, my tremor sends the cursor everywhere except where I want it.I recommend this as a replacement for a trackpad that is more efficient. I would not recommend this for an average user running any game more complex than walking simulator. With training, you could run this efficiently for most things that don't require split second reactions.This device would work well for anyone manipulating clickable interfaces in a productive manner.Great product very helpful with my wife’s hand and wrist issues.Great until the left button starts turning single clicks into double clicks (for me about 2 years, for many others event less). There are instructions available to "re-tension" the spring underneath the button but we shouldn't have to do that for a relatively new product. The issue has been known for ages so why Logitech is not sorting it out is a mystery. Avoid this mouse.First off I do/did really like it and actually bought a 2nd for work & home but there has been 4 vulnerabilities just found with Logitech's Unifying USB receivers that this mouse needs to connect to. They only plan to fix 2 of them next month and NOT FIX the remaining 2 vulnerabilities. .These vulnerabilities will allow keystroke injection attacks, record keystrokes, and take control of compromised systems. The only "slight positive" is they require attackers to have physical access. But in a work environment with many people passing through (colleagues, cleaners, delivery men...etc), I would not take the chance to use this device anymore.It is probably more a concern for their wireless keyboards (which I also have 2 of) but still not worth the chance of using the mouse in a work environment till the 4 issues are all fixed.Search for the bug references for more info: CVE-2019-13054 (they will fix next month), CVE-2019-13055 (they will fix next month), CVE-2019-13052 (they wont fix) & CVE-2019-13053 (they wont fix).In summary: this device will remain offline till they fix all issues (or if they replace with a free upgraded/fixed receiver). Until then, I won't be buying another wireless Logitech product again.Ya tenía la versión antigua de este mismo trackball, pero la versión con cable, decidí comprar uno nuevo porque me fallaba el botón principal. En realidad me daba igual que fuera inalámbrico, pero al empezar a usarlo enseguida me hice adicto a los dos nuevos botones para ir hacia delante y atrás en las webs.El caso es que a los pocos meses de usarlo me falla el botón principal (click izquierdo), como me pasaba en el antiguo, con la diferencia de que el viejo me duró años y este unos pocos meses.Si pulso el botón las cosas se seleccionan a medias, la única forma de que funcione es pulsando en el borde del botón.Me resulta bastante indignante que hayan usado pulsadores de baja calidad con el precio final que tiene, realmente podría devolverlo porque está en garantía, pero será para para que me dure otros dos o tres meses si me dan uno nuevo.Vaya forma más tonta de estropear un producto tan bien diseñado.El caso es que no hay otros trackballs para el dedo gordo, así que las opciones son limitadas y andar comprando uno cada pocos meses, aunque podría ser asumible, me parece un abuso.Lo que he hecho es comprar unos nuevos microinterruptores que funcionan mejor, tienen mejor tacto y son de alta calidad, por 1,5€ cada uno ahora funciona perfectamente y espero que por mucho más tiempo.Si a alguien más le interesa, el microinterruptor que he usado es el C&K ZMCJF7P0T (adjunto foto), el Omron y otras marcas no van igual de bien. Para desmontar el trackball hay que quitar 5 tornillos, 3 están bajo las almohadillas, 1 a la vista y 1 bajo la etiqueta de la pila.Para desoldar el microinterruptor yo he usado una estación de soldadura profesional, pero sólo tiene 3 terminales, así que es fácil sacarlo con un soldador normal y uno de esos desoldadores que son un tubo con un muelle que hace el vacío.List of problems I found with this purchase not just the item itself:1. link to the item in my order confirmation email (Jan 2019) is pointing out apparently to the same item "Logitech M570" but it's not! - the seller is different (at the time it was sold by "Online Saving" but now is pointing to "Logitech Store" - the product number is different, mine is 810-001807 not advertised 910-001882. - basically "Logitech M570" does not equal "Logitech M570" - it says the item is available since 2010 but this is not true since they sell multiple generations of these mice under the same name.The story about the item itself.Bought this mouse Jan 2019. Double click issue started in 2020. Not sure when exactly but it's over 6 months now. Was not suspecting this pretty new trackball mouse but system settings (OS software updates weekly - things can turn bad here or there) but had no time to investigate which settings can cause that click behaviour because I never touch the mouse settings - always stick to defaults.Initially it was on/off issue then the issue persisted.I looked on the web and found that people experience the same problem with this model but then after some digging I found that the mouse that was sold to me has a crappy micro switches which fail pretty quickly.Make sure to check the product number after receiving the item because they sell old crap hoping people won't notice.I think people who sell these mice also sell cars.Niente da dire sul prodotto, come tutti quelli logitech solidi e ben costruiti, la pallina scivola senza troppi attriti e i tasti danno una bella sensazione di solidità. inoltre la posizione del polso e della mano mi è sembrata più naturale che con altri mouse (perfino del mio logitech MX master).Io sono un progettista cad, nove-dieci ore al giorno davanti al pc col mouse in mano e, ogni tanto, il polso inizia a fare male. E allora sono settimane di sofferenza e antiinfiammatori. Sono incappato nel trackball cercando una soluzione per poter affaticare meno il polso, o, per lo meno, di una soluzione da affiancare al mouse per alcune applicazioni, ma purtroppo, dopo una settimana di test, devo dire che non è così: è molto meno preciso di un mouse (non è una questione di sensore, è intrinseco), muovendo la pallina col pollice è difficile puntare immediatamente a qualcosa, selezionare precisamente una parte di testo e così via: ci si avvicina all'oggetto e poi si "affina" la posizione con micro movimenti, ma è difficilissimo.Inoltre per alcuni comandi (ruotare un oggetto, per esempio) è necessario tenere premuto il pulsante sinistro e muovere il mouse. Il fatto di dover muovere il pollice con l'indice in tensione rende il movimento ancora meno preciso e gravoso per il polso.Insomma, probabilmente se fate un uso "normale" del mouse (navigazione internet e videoscrittura) non avrete problemi e dopo alcuni giorni non rimpiangerete il mouse, ma, nel mio caso , purtroppo, si è rivelato un acquisto sbagliato.
