When it comes to selecting gaming mouse, there are few things you are looking for:
Price -we will start with price because is the most important for most people. You want to get the best for your money, that’s a good thing and that’s what makes the free market run. The price of a gaming mouse is greatly influenced by the connectivity, the material used (better material = more expensive) maybe the ability to change resolution, precision on the weights, etc. A mouse with a more options will be more expensive. Well this is the reason bestgamersmouse.com exist, our aim is to make sure you get the best gaming mouse reviews and option to choose what you need and to be able to give your best gaming performance! 
Comfort – Most people ignore this aspect of a gaming mouse when comparing the price and quality. But, this is the most important thing – you need to be able to play for as long as possible without hurting your hand. A gaming mouse that is too heavy or too light will ruin the all experience of the game. At the least, a good gaming mouse will not feel uncomfortable for few hours of constant use.
Of course there are some other things that often get overlooked like amount of customization, precision, lenght of wire etc.
So, based on all of these things, and IMHO here’s how the current gaming headset rankings stand:
Razer Naga MMOG Laser Gaming Mouse -usability of this mouse is at the top of it’s class! The 5600dpi max resolution, 17 buttons etc. The best option in the sub-$100 price range. Priced at $80 ($70 at Amazon – this is a GREAT deal for the price now!
