If it ain't broke, don't fix it—tweak it. That's the idea behind the Logitech G502 Proteus Spectrum ($79.99), a solid, high-performing gaming mouse primed for personalization. The main difference between the Proteus Spectrum and its predecessor, the G502 Proteus Core, is the addition of customizable RGB lighting. These new lighting options don't really add much, but the mouse's sophisticated and comfortable design, 11 programmable buttons, resolution that's adjustable up to 12,000dpi, and removable weights make it a fine choice for most gamers. While the Razer Mamba ( at Amazon) is more expensive, its adjustable click feedback and superior lighting keep it as our Editors' Choice.

Purchased this gaming mouse for my son,and he loves it. He has had a few different mouses previously, but rates this one as his best one so far!!

Fantastic mouse

2 buttons including left click failing at 6 months

After purchasing this mouse over a year ago, the left mouse button has started to break down and incorrectly respond to inputs, after doing some googling it would appear that this is a very common issue for this mouse after approx. A year of use. If you don't plan on using this mouse for very long then I would recommend it, but if you plan on using it for a long period of time, > a year, be ready for the mouse to start acting up and not inputting correctly.

Mouse left click double clicks

If you want a fantastic wireless gaming mouse that offers a whole host of functions with one of the industry's best sensors, look no further than the Logitech G502 Lightspeed.

The HERO sensor is precise and sharp; Great battery life - 48 hours with full lighting enabled; Some brilliant backlighting functions;

Hyperscroll seems a little pointless; The removable bottom panel is a little fiddly; A lack of Bluetooth connectivity could be a little restrictive;
