Review on Black PERIMICE-720 Wireless Ergonomic Trackball Mouse With Adjustable Angle By Perixx - Boost Your Productivity by John Martin

I looked at a lot of trackballs and I only like the kind with the thumb control. I've had them for years and they are my favorite. Most mice out there are wireless and I don't like them. If you are a gamer and playing said game, some times I get lag from the wireless mouse. I'm less than 10 feet away, but still it happens. So the best trackballs are the corded.After looking at many trackballs, this one checked all my boxes and the price was a little higher (made in Germany), but I couldn't find any others close to this one. So I ordered it.In about a week it arrived and I plugged it in and it works great. I've had it for a while now and I can report no problems so far. Although it does require cleaning once in a while; with the inside the contacts.Reading the booklet it came with, it says to use the rubber end of a pencil to push the trackball out; so not to damage it. I've always had so degree of trouble getting the trackball out with others and found this trick worked really well. So now I use a pencil.Great mouse, I plain on ordering more. I like to keep a couple on backup, just in case I need another.
