At first all went well, good grip, good battery life. My computer has recognized very easily. Any deteriorated after 3days, yes 3 !! Autonomy 10 minutes, it turns off by itself in less than 2 minutes without use and once extinguished impossible to reuse before having set off and left good 10-15 minute charge (the laser lights up but impossible to move the cursor). In short I do not recommend. Even the price does not justify this invalidity. I was looking for a small mouse to play and not too expensive, but it did not even go for the simple office !!
