Pros: This mouse or another mouse with the same sensors is used by about half of all Quake Live professionals. It tracks flawlessly at up to 2 m/s, and 400 dpi is more that enough for all but the highest of sensitivities (side note: if your sensitivity is too high for this mouse, it's too high). Durable, ages well, the feet that come with it are pretty good, though you might want to buy teflon feet if you're super serious gamer. Super lightweight. Cheap as all

Cons: Cord is a little stiff, which can be a problem if you don't manage it properly. Scroll wheel occasionally glitches and moves one notch upwards, though you probably will only notice very rarely. In order to bring out its full potential the USB polling rate needs to be overclocked.

Overall Review: Overall, one of the best gaming mice ever. If you're paying $150 for a mouse, your doing it wrong, as Microsoft already came out with the perfect mouse: this one.

Pros: Gives me about 80 Mb/s down, 10 Mb/s up, which is the same as what I was getting with my onboard NIC (which was damaged). It installed immediately when I plugged it in, and worked perfectly. Solid build, a little bigger than I would have liked, but not overly so.

Cons: A little expensive, but seems to be high quality.

Overall Review: Works about as well as my onboard NIC did. USB 2.0 is fast enough for all but the fastest of internet connections.
