What is the bottom line. The ideal pressing of the main keys, (as on expensive mechanical keyboards) In my opinion, the backlight is ideal, the sensor, high-quality software, weight distribution, everything looks and feels super! Maybe this mouse is just not for me. Unfortunately. As a result, I gave it back with a pain in my heart. I ordered the SteelSeries Rival 500. It's worse, but feels good in the hand. And it doesn't fall out. So before you buy, check in the store for the rise. If it does, consider yourself lucky! ))) All the best and good shopping.
