30sixth 1.0I rated the MM520 as well. Some great shapes for me. I feel you.
rustRoach 1.0I have tried replacing my MM520 with these abominations. It's not the same. Can one company please just try.
Yes. I used to have a cooler master MM520. The finger rest combined with the hump towards the rear of the mouse was the best even though it had the absolute worst buttons of any mouse in existence. I have been looking for a replacement for at least 5 years now and found nothing.
