I bought this mouse for my friend who had just bought a gaming laptop. He hates using trackpads, and the one built into his machine is not to be desired. After I gave him this mouse, after he had been using a mini Logitech one for years, he absolutely loved it. The battery has seemed to last him well, but he always carries spares in his bag anyway, the response time is excellent (especially for a wireless mouse), and the clicking is silent (which is great for studying in public areas). Overall, this mouse is excellent for people not wanting to spend a heap of money but looking for a quality product.
