EDIT: After playing with the mouse for a while I found that it causes radio interference on the WIFI network. Not as bad as others. The interference is patchy so it comes and goes. I suspect that the radio periodically sleeps to allow other traffic. There is also an initial delay after 5-10 seconds of inactivity. I had high expectations, therefore - 2 stars for that. AT LAST! Bluetooth mouse that really sucks! I've bought many different Bluetooth mice for my work trips so I don't have to carry around a wired mouse or have a dongle and waste a USB port. They usually suffer from poor battery life, bad connection or strange connection. This mouse is perfect for work and works great with my work HP840. The radio doesn't interfere with your Wi-Fi connection like some Logitech mice do. And the batteries are AA quick-change batteries, not built-in rechargeable or proprietary types. If you're looking for a good, no-nonsense version of a work mouse, this is the one for you. It saves USB port, easy to connect and practical.
