I did hear lots of positive feedback about Razer Deathadder. But my experience with Razer products was somewhat bad. And keep in mind, I have had and used really a lot of their products: Razer Mamba mice (bought two), Razer Lycosa keyboard (they were two most expensive mouse/keyboard I could buy at a time, so we are not talking about cheapest stuff), Razer Megasoma (their most expensive mousepad), Razer Goliathus (which is cheap but btw quite nice) and Razer Destructor (probably their best surface), Razer Kabuto (meh mouse pad, attracts so much dust) and Razer Moray (quite nice earphones). My friend still has Destructor and I think he had no complaints. The best think I like about mamba is comfort which is much better than Logitech G7. Btw I had the exact same bug with Mamba. The cursor gets stuck to only vertical movement. Interesting. My friend from Europe had some experience with Roccat headphones and their gaming mouse and they seem OK so Roccat may be worth checking out. The only reason I highly recommend logitech is because I just used their stuff for SO long basically since I had my first computer I used Logitech mice. It's just when I was shopping for mouse they did not have laser wireless mouse. (G7 went out of production and nothing similar came in until a while.)
