As said in the title, this mouse is perfect! Very functional, I was even afraid that it is too hard to master, but in the space of a few days, it's as if you had for years. Great finish from Logitech, and shipping / delivery to the top too! I highly recommend it to anyone not want to slam astronomical sums in Razer products, this mouse is much better than the Naga in my eyes, and cheaper. In short, 5/5!
