Cool mouse so relaxing............................

I got for my gf who is a trackball user and she loves it!

We do a LOT of printing on our Epson and the 220xl's are the way to go

Convenient, easy to use, compact and comfortable..

Great Wireless Trackball Mouse. No pain in my fingers anymore.

Love the track ball technology. I have had 5 of the M-570 track ball mice in the last year and none of them worked. I had one that lasted 5 months and that was a record. The ball loses connection constantly and you cannot control the courser. The reason I purchased is that I had one that I used at my office that last 4 years but they must have redesigned it because the new ones are not worth the plastic their made of. DO NOT BUY!!!!!!

Purchased because I prefer trackball mouse to regular mouse.

My wrist doesn't bother me when I use this mouse. It's a bit touchy sometimes, though, occasionally the cursor isn't as precise as I'd like it to be.

Well, my daughter needed a mouse because her logitech mouse died at a young age so we hooked this wireless mouse up and it started working immediately. Works really good but the buttons are hard to find and are a nuisance. The on/off light doesn't stay on and the switch is underneath and is hard to turn off. I liked the older marble mouse better because I could use it without my fingers wandering around searching for the buttons. Not bad but could be better.

I only buy this trackball because its the best for the money

It's a little bit pricy, yes, but it's resistant, simple and practical.

I've been using Logitech or years. Always dependable

Some times the ball gets stuck. Conencts with unifying receiver well.

Very Convenient, Helpful, Modernize and resourceful.

The thumb ball is hard to navigate. If you turn it, it won't function.

It is easy to connect to your PC and it works well, but wait until you need to move the cursor in a precise manner and you will soon be cursing. Other than that, it is OK but not for me.

Seems OK but takes some getting used to if you're used to a regular "center position ball" trackball. Using the thumb for scrolling will take some days/weeks to get good at using. Can't understand the decision to drop Bluetooth connections in favor of Logitech's proprietary wireless to USB dongle approach. And if you lose the small (and essential!) USB plug-in, how much do replacements cost? More than the mouse I'm guessing LOL. So it can't be used for a computer without USB like iPads and some of the new laptops, seems pretty dumb to abandon using Bluetooth for wireless mouse. Would not buy again.

Used for a week, okay experience as far as comfort and ease of use. Then one day after using, thumb starts hurting bad. A waste of money as have had no choice but to go back to a regular mouse due to daily thumb pain.

I bought one last week and I was disappointed as soon as I started using it. The trackball sits loosely in its housing and requires a lot of effort to get it to track across the screen. The mouse feels very cheaply made.

Bought this to replace my old, came-with-the-computer mouse that I have to keep picking up to move (I have a newer, larger monitor). Tried every USB port available-cursor still wouldn't move.Tried everything short of taking the mouse apart like one other cosumer did (I'm not savy enough to do that), still couldn't get it to work.
