HP X4000b Bluetooth-Maus, Beidhändig, Laser, Bluetooth, 1600 DPI, Schwarz

Thank you amazon. Delivery in less time than advertised. Product according to specifications. Complete. In good state. Thank you.

The lack of instructions coupled with there seeming to be no way to open it, made me very displeased; it seemed to be a "brick" as far as function went. Then a girl pried off the button surface with her long fingernails and revealed the solution of where to find the USB transmitter and where to insert the batteries. Usually access to these things are from beneath, and the lack of instructions made it a very frustrating experience. Also, be warned that it takes a while for the device to sync, making it seem like it doesn't work. Again, instructions would have been most helpful in this regard.

Received this yesterday around 3:30 pm and the batteries already died by this morning @ 5 am. It's also a tiny little thing. A shame because it seems to track much better than other wireless devices I've tried. So far very disappointing. Hopefully things improve with the new batteries, but if they die in 12 hours I'm returning this. Very frustrating. Update: I think this mouse was used because the initial batteries died in under 24 hours, the packaging was a bit beat up and had tape on it, and most of all, because this mouse is terrible. What a disappointment. I'm so tired of crappy useless wireless mouses. I guess this could be ok if it were new? I don't know. Save your money IMO.

Not much to say, battery life is terrible, and stops responding all the time

This product is not as smooth as I had expect it to be. Over all it works.
