Durability and comfort
It's now 4 years since I bought this mouse and I'm not disappointed. First of all, it's comfortable, it fits the shape of my hand well (very subjective and depends on the person) but it's soft to the touch and has a good grip. It feels good even after hours of FPS because it's not too heavy, but you don't feel the weight of the cord (about 2M?) either. It also glides very well over a carpet, with no annoying or unpleasant noise or friction. In terms of settings, there's everything you need, including an easy switch between 2 configurations at any time. It's just starting to show a few signs of fatigue on the right click after 4 years of almost daily use. But I'm delighted with it, and hope to find a successor that's up to the job.
