Review on Ergonomic Vertical Wireless Adjustable Removable by Vanessa Johnson

I bought TWO of these. once wireless, once wired. I like their SIZE compared to the ergonomic ANCHOR I usually use. The Delux are also nice and heavy and feel good in the hand. However, both stopped working - in particular the LEFT and RIGHT mouse buttons stopped registering clicks, even with updated driver software. First one I bought in December (wireless) thought maybe my button is worn out from using it to play games. I bought a new one (wired) a few days ago and as soon as I plugged it in the buttons didn't work. I tried it on two different computers with the same results. I've decided to just use my Anker 2.4G wireless which still works great after all this time (first bought 25th October 2014).
