I used to change mouse every 2 months till I bought HP X1000. Used this mouse for 1.5 years and then tried various high end gaming mice. Didnt like anything and ordered this again.
Pros: Everything lol. Looks like 1000 DPI is my sweet spot. This mouse works well on wooden surfaces and you dont really need a mouse pad(Although recommended since it will accumulate dust if you dont use mouse pad). Awesome for gaming, amazing precision since it is extra small and light weight. Find this mouse a 100 times better than Razer Abyssus which I used for 2 weeks and threw away. If you are a finger grip gamer just go for it, there is nothing branded in market except Roccat Pyra that is actually finger grip mouse.
Cons: Once you get used to this mouse, you have a terrible time adjusting to anything else. Its an extra small, extra light finger grip mouse, so you have palm grip and are used to a heavy mouse, I suggest you dont buy this mouse. You will easily adjust to this small mouse in 2 days but you will take a month to adjust to other mice after you use this.
