Sharkoon are a good company that are seriously under-estimated because people are used to paying 100 or more for peripherals. They make good products aimed at normal human beings, not just aspiring pro-gamers and teenagers with too much disposable income. I'm really happy to see them go into the super-low budget world. Now not even the most budget conscious people need to use a crappy two button mouse ever again.
I'm sorry you guys had a bad experience with Sharkoon, but I've had my Fireglider about two and a half years and it's been awesome for me. No signs of wear despite my sweaty palms and psychotically heavy use (I work from home much of the time). It cost me £25 and you'd have to offer me something three times the price made by Razor before I'd think about switching. It's good, it's comfy, the software let's me make very complex macros if I need them, and the 7th button set into the left button is amazing. There's so many games where you do 'something + click' and you do it all the damn time (Attack move in starcraft for example). That seventh button is perfect for that and I have yet to find another mouse with that button in that position even though it's so comfy and so useful.
