Very comfortable grip, works with almost all the games i have for pc. For those who say it doesn't work with vista it does, vista finds and installs the drivers automatically so no need for the disk. And the drivers are also fine, i haven't run into any problems whatsoever.
Don't hesitate to buy this just because of negative reviews, its cheaper than a lot of other controllers but it is a lot better than any other pc controller i've used. The lengthy cable that comes with it means i can sit back on a sofa while playing games.
This makes especially good for racing games like Pure or Need For Speed.
If you've already used a 360 controller then how great these are should need no explaining.
