Gazzew Boba U4T Thocky Tactile Switches

Awesome service!

Appreciate the offering. Everything came in great and quickly. Very satisfied. Would shop with you again. Switches were lubed consistently. Buttery smooth. Thanks!

good switches, lubing/qc can be better

Only got the pack of 10 lubed (no films) to see if I like them. Switches are good, but I have a bone to pick with the service. 1) On ~6/10 switches, the top housing was not closed properly and the switches wouldnt go into the socket, so I had to manually reclose all 10 of them before they went in, 2) order took twice as long to process as mentioned on the website (order to ship 14 days), 3) 1 of the 10 switches was delivered defective and makes kind of a plasticky/crinkly/popping sound every couple of keypresses.


Exactly what I needed! Perfectly lived and filmed. Thank you! Keys sound/feel delicious.
