The back plate which is supposed to cover the batteries is flimsy and falls off repeatedly. This means that the batteries will fall out - again, repeatedly. A bit of tape over the back is not enough to retain the batteries whenever the mouse, for instance, falls off the couch or even to the side of user. Other than this design flaw (pretty major in terms of functionality) the mouse does track and respond well.

Good fit in hand and light. I dont like a big mouse but this one is perfect as it fits nicely in my hand. Easy as to use

Bought on Sunday as our existing Mouse died. Put in the batteries that were included and an hour & a half later they were flat. Replaced the batteries and they've not even lasted two days. Our old mouse would go months on the same batteries :-(

Stopped working after only a month

Brought this mouse as part of a mouse and keyboard set. Squeaks so much and so loudly that have had to replace.

I brought this brand of wireless about a month ago. And today it stopped working! I turned off the mouse & left it off 2 minutes before I replaced the batteries in it; which had the ones that it came with still being used. When the mouse light didn't come on it I thought there was a problem with the receiver in my laptop so I shut down my laptop waited another 2 minutes than tried another USB port for the receiver than I turned my laptop back on & there was still no light. I'm having to use a USB wired mouse until I can get another wireless mouse. Though I won't be buying this brand when I get the new mouse. I know you get what you pay for. But, I was expecting my mouse to last longer. To anyone thinking of buying this brand; DON'T. Buy, another brand instead
