I purchased my third bluetooth mouse in a year today. The first was a Level-One BLM-3000. Quickly abandoned on grounds that it wasn’t comfortable, had poor battery life and frequently lost receptivity – leaving me wondering whether it was time to change the batteries again, or just something wrong with the connection. The second was a Microsoft Bluetooth Notebook Mouse 5000. A good mouse, but recently the middle button wore out – apparently from over-use (mainly from opening browser tabs). It still works, but only when pressed hard and long. Today I replaced this with a Logitech V470. It’s a good looking two-tone grey and white, and is comfortable. One nice feature is that it takes regular AA batteries, rather than lower capacity AAAs. I just hope this mouse stays with me longer than did the other two – Bluetooth mice or not cheap.
