TECKNET Bluetooth Wireless Mouse 4800 DPI

The battery cover is actually the bottom part of the mouse. I never seen such a stupid design and low quality plastic parts in my life. The cover is actually falling off by moving the mouse. Even the cheapest mice never had a design flow like this. This nullifies the value of the otherwise ergonomically nice product. DO NOT BUY IT. It was meant to be a gift to me daughter, but ended up buying another brand instead this.

It connected very easily and worked the first time. 2 days later my laptop doesn't recognize it!!

Didn't go all the way down on the rating due to the mouse connecting and working well. The power save feature is the cause of constant frustration though. All it takes is a reasonable conversation leaving the mouse dormant and the power button must be cycled to reactivate.
Time is worth more than the cost of the batteries. At least it could have an option to lengthen the time for dormancy.

I ordered two of these and one works flawlessly, but the other goes to sleep and drops connection to computer. When I move it, it wakes up, but after a minute of use just stops working. I have to go to my worn-out Logitech mouse which is what I was trying to replace.
One is great and the other is garbage!

I mean sometimes it works perfectly but other times it just doesnt react to movement. like the cursor just wont move. this could be due to my surface but ive used it on multiple surfaces (mousepad, wooden desk, paper, the hard cover they put on notebooks) and its very unreliably on each surface. its a cheap mouse so i cant really complain but i think it still should be said. 2/5
