These silent tactile switches significantly decreased my overall typing volume and will make my office mechanical keyboard much quieter and more suitable for a shared office environment. Would definitely recommend Thock King!

Filming makes the switches louder

Skip the filming process. I have Boba U4 unlubed switches, both on Keychron V-series keyboards and both using Keychron White-on-Black PBT keycaps. And the un-lubed/un-filmed switches are way quieter.

I'll never buy filmed Boba U4 switches again. Boba U4 switches are great, and ThockKing did a great job - but U4 switches just don't seem like they should be filmed, ever. In fact, some switches popper open during shipping, and when inserted into the keyboard would pop open due to the pressure from using the film. Lube-only for Boba U4.


Wish I picked up more

Quiet and tactile

I was looking to try out a silent tactile switch and landed on the Boba U4 silent. I picked the lubed option as I hadn't tried lubed switches before. That added an expected week before shipping. They arrived on schedule and they feel and sound great! I was a bit wary of trying thock king but it was a good experience with great switches. We'll see how long before I'm ordering more!

Work perfect

They are super quiet and exactly what I was looking for. Great service and quick turn around for delivery. Will definitely be ordered the next set of switches i get from Thock King.
