I've always hated Logitech mice. They never handle properly, I begin to suck at FPS deathmatches whenever I use Logitech mice. The OCZ Behemoth looks too big for me; I like smaller, light mice that really let me aim properly.

I have a bit of a peripheral fetish too, I have 4 mice on me right now, 2 Logitech and 2 A4 Tech (a largely unknown brand that IMO has better mice than Logitech). I always fall for Logitech though because their packaging is so sweet. Even if functionally they are not my thing.

I also have 4 keyboards one normal one, 2 Logitechs, 1 A4 Tech Gaming Keyboard and 1 Belkin N52 TE -- which I should also review. I couldn't really get into theBelkin, though, cool and geeky as it was. It just didn't have enough buttons; as someone who's been playing FPS for more than a decade certain controls had been hard-wired into my muscle memory and using 1,2,3 and 4 keys for switching weapons was one of them; this was the Achilles heel of the Nostromo N52.

I see Chris you have a Dinovo; I didn't get the Edge, but I got the Mini, because I needed a small keyboard for home theatre use. I must say, it's rpetty shoddy and way overpriced, but it's pretty cool. It's not totally usable though; it powers out way too much and it takes too long for bluetooth to reconnect from sleep mode. Overall I guess I'm not happy with Logitech; they are an overhyped brand for all their peripherals except their speakers, IMO.
