I had constant problems with the USB-Bolt receiver, terrible! I tried a lot and it kept jerking and stopped working. After disconnecting and reconnecting it worked again a bit. But not for long.
I then tried Bluetooth even with a cheap adapter on my old PC. Works very well, since then no problems for anything, for my applications in the office.
The new Bolt technology with the USB receiver didn't work for me! Not even with the Logi SW and x updates.
I wouldn't recommend this mouse for fast applications such as gaming etc., but it works very well for office connections via Bluetooth.
