It's xmas gift, these switches haven't been tried yet. I am sorry for such review but the aliexpress presses me to write something so here it is. Any potential problems shall be blamed on Santa :D
My favorite switches thus far! Kailh shipped these almost immediately but the shipping took 4 weeks (this was not the seller's fault). I've tried the cherry mx series, gateron, regular kailh box switches, and now these silent box browns. And I got to say, I'm very impressed with them. At the beginning of my interest in mechanical keyboards, I thought I would be interested in linears. However I noticed I was having a difficult time typing. I kept making mistakes, and felt that it was slowing down my typing speed. I tried the regular box browns, and I loved them however I gave them to my husband since he recently received his mechanical keyboard. I decided to get these silent versions, out of curiosity. I wanted to see how well a switch can be being both tactile and silent. And wow, it's been a dream! They feel exactly the same to the regular box browns but just muted (?). My typing experience has improved significantly and I believe I will use this as my main for awhile.
