Review on TeckNet Portable Wireless Receiver Adjustment by Leonard Beard

SEE EDIT BELOW. This mouse worked fine when I first got it (although I compared it to a mouse that was intermittently unresponsive) but after the last few months of use the sensitivity seems to have diminished. the worst. Now it's very jerky and hard to use when I need to be very precise - even trying to fast forward a video can be a chore because it skips the playbar/dot up, then down, then up - You get the picture. I think for the price I'm glad I lasted a few months but wouldn't recommend this to anyone looking for something that will be used frequently and for the long term. Of course, I spend about 10-12 hours a day on my computer, so I'm also a heavy user. I personally will just spend my money on Logitec in the hopes that I can stop replacing all the gaming mice (mice - I don't know) I've had to buy. EDIT: I am updating my rating to 4 stars because I was contacted by a customer service rep offering a replacement or refund. I keep my original comments because they matched my experience but please note that if you buy this you can BUY WITH CONFIDENCE as the sellers stand behind a quality product and back it up with their customer service policy. It's possible I just got a lemon.
