Do not waste your money on this one you’ll just have to buy another one very soon not durable at all I guess I can’t handle rolling around a table

Not smooth at all. Scrolls up randomly while trying to scroll down and vise versa. Get what you paid for….

Scroll dial down, it automatically scrolls up & down (frustrating). Sometimes can't find cursor, need to wiggle it, just a little bit to wake it. If you're not used to the placement of the page forward/back button at thumb, it's easy to accidentally bump and back out of the page you were working on.

Not the most comfortable mouse and the scroll wheel sucks. More often than not the screen moves the opposite way from the scroll wheel.

So I ordered this thinking my old mouse was dead and I needed something inexpensive to replace it--and fast. It was indeed fast, but after I ordered it, I discovered that the problem with my mouse was that the battery was dead and I kept trying to get it to work with the battery inserted the wrong way, so I didn't need a new mouse after all. Yadda yadda yadda, I didn't open it for a month and when I finally did, I discovered that the USB device that makes it work was missing. It'll take more effort than I care to exert to return it, so I'll just consider this my $12 mistake for the month.

Every single time I want to use this mouse I have to remove the battery and put it back in. It does not 'wake up' as it's supposed to.

The mouse worked great for about 3 months then it went on the blitz. Worked sometimes but most of the time it doesn’t. Continuously freezes and makes it extremely difficult to get anything done.

This mouse is 4 weeks old and the scroll function is all over the place. When scrolling down the image keeps bouncing back up. One must scroll very slowly to have this work at all. What a frustrating mouse. Too late to return. Another useless purchase from you know where.

I don't remember if I initially left a 5-star review. Today, I'd only give 1 start. Beside the nice price and ergonomic design, the scrolling function is broken after around 2-3 months. It is always skipping back, sometimes stop working when browsing or reading a long web page or a e-book. Can't find a way to contact customer service for warranty. Tried on Amazon contact link, somehow the party I contact, saying they are not doing anything...

Goes into sleep mode frequently and takes forever to get it to come back on
