Prior to that, I used Chinese cheap mechanics (HERMES), which rattled, whistled and stopped normally pressing characters after 2 years. Asus turned out to be simply divine after Hermes - the keys do not play, the pressing sound is very pleasant, it works instantly, what else do you need from it? In games, it behaves incomparably, but it will take some getting used to typing due to very light pressing. Before buying, I pressed other mechanics in different stores - almost all of them bled from their ears. I really wanted a branded soft wrist rest from asus, but it's not included here, but it's very expensive separately, I ordered it from alik for 700r - it's rude but it will do. There is no ultrasound in my copy, but Hermes had it.
