Replaced my old set in my keyboard with these ones and they works great.

I bought these for mostly for the caps lock key which I was accidentally hitting with light contact. I ended up putting them in for a bunch of keys that suited my sloppy typing style. The higher force was perfect to prevent accidental activation and still allow for smooth action. Creates a pretty loud thock.

If you are an old-school typist with proper form, possibly have heavier hands, this is the perfect switch. I had glorious pandas, which I hated, and which started to degrade/fail within a year. They also nearly had to be bottomed out to activate--especially with use. These BULLET-F switches have an amazingly stable and predictable feel, with the perfect point-of-no-return near the top of the stroke. They also bottom out a 3mm, making typing faster than a 4mm switch. I love that there is almost no pre-travel feel. It goes right into the pressure point and then it's an instant drop off the cliff. My typing speed and comfort has gone up considerable. This is by far my favorite switch after trying so many others (kailh box blue/jade/white and non-box brown).

These switch are exactly as advertised. Sound is great if you don't like the more click sound. I am getting another set to finish out my keyboard.

I like non-clicky strong tactile switches. The current switch I am using is Glorious Panda. The Wukong switch has similar spec numbers, and very affordable, so I want to give it a try. It turns out pretty nice. The Wukong switch has a tad stronger tactile feeling, and a tad greater activation force. (pressing two switch stems against each other, the Glorious Panda always gives in first.)
In terms of sound, Glorious Panda is more crisp, Wukong is more muted. Both sound good, I like Wukong a bit more.
I ended up using Wukong switches for my home keyboard, and move the Glorious Panda to my office one.
Just onething to note, the spec sheet says the Wukong switch has some pre-travel. My own experience actually shows no pre-travel.

BTW, Wukong in Chinese stands for ���, the name of the Monkey King in chinese mythology, which every Chinese knows. I have no idea why it is named this way, probably because the red-yellow color theme of the switch is somewhat close to ���'s costume color theme. The red case matches well with my black keyboard. I put on low profile keycaps to expose the red color more. It really looks nice.
