This mouse just replaced my viper 8k and viper mini. Clean and clear sound with touch of bass Its lightweight, the little handles make it super easy to move. was so happy when I found I could get these in a size 2. Overall this is a good solid protector and I expect it to last a really long time. update a few months along , the unit now fails to work at all , utter garbage. " How dare she, right?One, maybe even two breaking like this, sure, thats user error. This is a cute little shelf. I feel it holding everything in. I found that the ANC on the Ankers is actually not that far behind the Bose (and definitely better than TT).
