Summary: I haven't had much luck with Bluetooth. I am not sure if it is the keyboard and/or mouse that go to sleep when not used, but when you are ready to type, you have to hit a non-character key to wake it up, otherwise you miss the first 1 or 2 characters. Same with mouse; you must wiggle it to wake it up, then move cursor to the target. You get much better response with wireless instead of Bluetooth.
Summary: I have an old, moderately abused ASUS hand-me-down with two of the three USB ports messed up (devices left in them and the tabs broken off so they can't connect to cables) by the previous owner. I wanted to set it up as a thin client to my main computer. I had an extra wireless KB that didn't come with a wireless mouse, so needed a mouse (touchpads are not an option for me). This mouse serves the role for limited functions.
Pros: Connected to computer just fine. Worked once I had all the BT ancillary drivers installed. Any surface laser eliminates need for mouse pads.
Cons: No programming or button allocation drivers (strictly a basic mouse). Kind of choppy for fine work. Somewhat loud clicker (A mouse pad or soft surface helps make it quieter).
Pros: It's a full-size Bluetooth mouse, which is pretty rare in this price range. It connected immediately, works on any surface: desk, fabric couch, jeans, skin, etc. It's about as accurate as a wired mouse of the same caliber. Range is great from 20-25 feet away. It comes back from PC idle/shutdown 100% of the time. Windows 8 x64.
Cons: Every rare now and then, the mouse, while being used will simply stop working for about 3-5 seconds. Then it comes back and works great for a few hours with no problems. This is used on my media center PC, so it doesn't bother me enough to RMA it, but I will knock off a star for it.
Summary: Plus - good battery life,cheaper minus - too big for portability, stops working while browsing some web pages-need to re-install more than 3 times during each browsing session.Sony vaio BT mouse far better in performance!
