When my old Logitech mouse started to give up the ghost I decided it was time to go optical, and while I was at it, why not wireless too. I expected that I would have to sell my Grandma to go down this route, so was pleasantly surprised that £30 would buy me a Trust AMI Mouse 250SX Wireless Optical. First impressions are that it is a quality product. It has a nice weight to it, and looks stylish in silver and dark grey. It is also very pleasing to hold, and fits into my cupped hand perfectly. It is a five-button mouse wheel mouse, with two programmable buttons on the side. The left hand of these buttons can be easily operated with the thumb, but the right one is a bit awkward to use. Setup was simple. The base unit has a standard PS2 connection, so it just plugged in and replaced the existing mouse. Windows XP didn't even need to change drivers, it just used a standard PS2 mouse driver. Then you just plug the batteries into the mouse, select a channel (a bit like you would on a baby monitor) and away you go. Rechargeable batteries are included with the mouse and these will need charging up initially, and from time to time in future. This is done by linking a cable between the mouse and the base station. The batteries can be charged while the mouse is in use, and if you have a PS2 port that provides power while the PC is switched off, you can charge the batteries even with the PC off. Initially the mouse felt totally different to use that anything I was used to. I had to ditch my trusty mouse mat and just use the tabletop, and it just didn't feel right. My wife is less patient with these things than I am and she had the same problem. I thought we would have to give up our new mouse and return to our old ways, but then it just changed. I don't know when it changed, but it did, and now it feels right. I like the way it glides over the desk and doesn't get snagged and I like the way we can now both use the computer and pass th
e mouse between us without tying the desk up in knots and I wouldn't go back now if you paid me.
