Customer Ratings & Reviews

I’ve been using this mouse type for a large part of two decades. I like the fact that my arm stays immobile the whole time. This helps me keep further injuries away. That being said, I don’t think this would work for people with arthritis in their right thumb or who have to draw (and can’t hold a stylus for long periods). But for me, I will take this everywhere I go. I was not gentle on it when I traveled; the mouse usually ended up at the bottom of my bag getting set repeatedly on the ground and squished by heavy things from the top. They still last 4-8 years for me.

This is the 2nd time I have purchased this same mouse, it lasted me about 4 years with heavy use. It is a very good mouse for those who like using a trackball. I haven't had a single problem with it.

this item works pretty good. i don''t prefer to have a mouse with batteries in it, but the batteries seem to last pretty well in the devise. i usually prefer the mouse with the ball in the middle of the top with buttons on each side of it. after using this one for a bit i have gotten use to it.

now i have one for each of my pc's and no complaints!

Wireless mouses can be expensive and lower priced models can be lower in quality. This mouse has a great price and great quality. Definitely worth it without breaking the bank.

Have been using Logitech M570 Wireless Trackball for many years. This purchase was to replace an old Trackball which had finally given up the ghost. I'm lost without the M570.

I have relied on this mouse for many years, will buy another one for years and years as long as they are in the production, never hurt my hand ever. ordinary mouse hurts my hand within 15-30 mins.

I love my mouse. I got it because I use my computer 10 - 12 hours a day. This mouse allows me to position my hand comfortably, and it maneuvers beautifully.

Owned a previous trackball for years. Never an issue.

This track ball mouse is perfect for use on laptops. fits nicely in ones hand doesn't require any space to move mouse around. you can set it on a chair arm , or on your leg. great surfing at your finger tips

Needed a new mouse because I was having pain in my wrist/forearm area. This mouse has been key to making me pain free. I haven't had any issue with it and it was pretty easy to use right out of the box.

Initially I thought it has both optical and track ball, later I found it doesn’t have a optical tracker. It took little while to adopt, but now I love it

Love it. Using the ball is easy on your hand. It makes navigation easy. I love that the mouse is stationary so you do not have to get hung up in a corner of the screen, or cannot find the arrow b

If you are looking for an ergonomic mouse, this one is great! Very comfortable, no glitches or skips, can always find my cursor, etc. Definitely recommend.

great mouse and super comfortable to use. I can really move the mouse around with the thumb ball. you can set it to the perfect settings.

Son loves the ergonomic shape. Great for gaming. **

Was easy to install, best trackball mouse I have found.

I love using the trackball feature but would like to use both trackball and mouse movements. It has tons of features but I’ve only use the simple ones.

Works as it should. Got a track ball due to lack of space to drag a mouse around. Works great. Software let's you connect multiple devices to the wireless USB.

One less wired USB transmitter to deal with. done!
