Also keep in mind that this has a laser sensor, which is not a precise as optical sensors. I have a g700 with a laser sensor, and while I do like the mouse a lot, the difference is noticeable if I pay attention compared to my brother's mouse.
It's the PTE, which has its own problem, but it has no hardware acceleration. G700 laser =/= PTE
In regards to the mouse, I really liked mine, but I have decently large hands and love a palm grip. If you use a claw/fingertip grip, this mouse is probably way too heavy for your playstyle.
As mentioned below, It's probably a bad choice for low-sensitivity players, but I play at a high sensitivity, so I had absolutely no issues with mine. I only stopped using it because I borked the cable, and that could easily be fixed with a bit of soldering.
