I also got this switches with a cheap keyboard, and I'm very surprised. I've never been a fan of cherry's blue but this ones are a little different, they feel snappier, and are pretty smooth.
The sound it's still thin and plastic like the MX, a little different, but still it's not that sound that makes you fall in love, but it can be tolerated, it's not that bad.
I got these switches with a cheap keyboard, they work really well. Buyer beware: the pins will bend easily. Other then that it works great.
