It is just a waste of money , keeps on disconnecting in 5 minutes have to switch on and off and waste a lot of time during work go for a USB mouse they are more reliable than bluetooth ones and consumes less battery.

Very bad product... buy logitech instead of this cheap alternative... i have wasted my money... sensors are poor quality... bluetooth losses signal every 5 seconds. Needs to restart the mouse to reconnect... will make you completely unproductive... DON'T BUY!

Superb product. Working nicely with my dell ultrabook. Quick connectivity.

I am using this for last couple of months and it seems to be a nice product For its price, although it can definitely be better.
No issue while connecting and also very responsive for clicks and movement. Connection is also stable and fluent.
An issue is it goes to sleep very quickly, at one side it saves power but at the other causes irritation while working.
