Logitech Cordless MouseMan Optical

The mouse is great for general use (such as surfing the web or for word processing, etc...). I was also very impressed with its performance in games; Half-Life works really well with it. However, technically the mouse has a (slow) refresh rate of 50Hz which is not as fast as some of the corded optical mice which does annoy some hard-core gamers - but I have not noticed any difference.

Although this mouse is really great I have noticed that the mouse's response is a little dodgy if you do not follow the instructions about the receiver. You need to place the receiver 20cm away from anything which gives out radio frequency radiation (including monitors and speakers as well as the PC itself). The battery rating is also a bit of an exaggeration - your mileage will vary depending on what surface you run the mouse on. Darker surfaces use more battery power than lighter coloured surfaces. However, you can run this mouse on rechargeable batteries contrary to some reports. I run mine on Uniross Ni-MH batteries that I got for about a fiver and I find that I have to re-charge about once every 2 and a half weeks - but it's well worth the hassle.

After the first 1 and a bit months that I've had this mouse I have to say that I would never go back to mechanical or corded.

The battery life is staggering. I've been using it on most sensible surfaces, including fairly dark ones. I have yet to find one it will NOT work on, though I suspect that both glass and completely black surfaces will reflect too little light to be detected (well, DUH!). It's on constantly (no switch on it), and shows no signs yet of failing.

Gripes? Well, since I use it with a laptop, it would be nice if it was smaller. I suspect it's too big to be used by kids, but then, who's going to spend fifty quid on a kid's mouse anyway?

It would also be nice if it was more ambidextrously shaped. I'm left-handed, and while I'm used to using a mouse right-handed, it is nice to swap around sometimes. Having no cable should make this easier, but the shape is just WRONG: it is NOT usable lefthanded (unless you have very funnyshaped hands).

Ability to recharge would have been nice, but given the battery life, I don't think it's necessary.

So in summary: best thing since sliced bread, unless your desk is black or glassy, you are completely lefthanded, or you are a child.
