I had a Razer Mamba for ~2 years but the cable was starting to fray and the tracking was becoming unreliable. I started looking at some of the newer mice, and I was looking for a mouse that wasn't too over the top. For me, the Corsair M65 came close, but that obnoxious sniper button on the side killed it for me. Then I came across the Logitech G502 Proteus Spectrum. Having owned an MX series mouse in the past, I'm a big fan of the toggle style mouse wheel (toggle on/off to freely spin). I also really like mice that have a thumbrest along the side so you don't drag your hand across your desk/mousepad all day, especially for those of us who work on a computer all day. Finally, the adjustable weight system is great. By default, the G502 is a bit too light for my liking so I just arranged 3 of the 5 ~3.5 gram weights evenly in the bottom; the results were perfect. For anyone who likes RGB, I'm sure you'll like this mouse, but personally I didn't buy it for the RGB and could really care less what color the G logo is when my hand is covering it. Still, I suppose it adds a subtle good look to the mouse without going overboard. Overall, a great mouse that I expect will last me at least a few years!
