Scroll wheel doesn't move the page smoothly. It consistently jerks the page in the opposite direction I want to scroll and after a few very jerky scrolls it finally goes in the direction I want. Still jerks up and down every few scrolls though and overshoots my stopping point and then we go through it all over again. Gave up on it. Way too frustrating.

First time I have ever purchased a mouse that did not have battery. I had an extra at the house, so I used it but how cheap can you get. My bad. Not worth the time and effort to send it back. Lesson learned.

I've been putting up with the scrolling future for a few months now. I review a lot of documents and websites at my job and I have to scroll twice as much that I normally would on my old mouse. It is not fluid and smooth It's incredibly frustrating and now I'm buying a different mouse.

Received it in June, and have used it daily. But by October it began having wheel slipping issues. When scrolling with it, it would jump around, or not move at all. Went back to my USB mouse.

I really liked this mouse for the first week, but the tracking started to not work. The mouse would stop moving across the screen randomly and skip a lot. Its a very cheap mouse, so I guess you get what you pay for. I just wish it had lasted longer than a week.

This mouse worked perfectly fine the first month. I purchased July 12th and had no complaints. Now it is August 19th and this past week it has decided to just do its own thing. If I try to scroll up or down, it might do it or it might not. Sometimes I will be scrolling down and it will start scrolling up on its own. I work in a fast-paced office and do not have the time to be dealing with it. I will have to replace because the return window conveniently closed this past week also.

I like the functionality... small footprint, wireless works great, battery lasts a long long time. Though it goes to sleep after 10-15 minutes requiring a button click to wake up in order to achieve this battery life. Small trade off and easy to get used to. What is NOT easy to get used to is the scroll wheel. When trying to scroll down the screen constantly bounces back up unless you scroll very very slowly. It's nearly unusable for this reason, especially in documents. I have two of these, and both do it. Wish I had bought something else.

I bought two of these and both scroll wheels worked fine for about 3 months. Now both are useless. They both scroll but not always in the correction (i.e. jumps around). I use the scroll wheel constantly so these are going in the trash. They were cheap, but there are other cheap options out there from well known brands.

I've had the mouse for about 7 months. Which in some way goes to show you that overall I really do like the mouse. However, the scroll wheel is truly bad. When scrolling, it will almost always glitch and move the page both up and down. Not that you cant use the scroll wheel, but it's a two step forward one step back type of thing. This is accelerated when you scroll fast.
