Keychron S1 QMK Custom Mechanical Keyboard

Great, with some quality control issues.

After about a month of everyday use - this is the best keyboard I ever owned. Compared to my previous K3 the S1 feels much more solid, it's heavier and sturdier. It sounds and feels great. I would have rated 5-stars if it wasn't for an annoying assembly/quality issue I had to deal with (described below). The above opinion is unfortunately after some tinkering and initial disappointment. After receiving the keyboard and plugging it in for a test run I noticed that the left Shift key feels a little spongy, much different than the rest. The Enter and Backspace key, which are of similar size and use the same stabilizer mechanism felt completely different. I pulled off the keycaps to compare - the Shift key's stabilizers were completely flooded with lubricant. I wiped the excess off and also swapped the switch itself with some other key, just to rule that out. I hoped thought it would smooth out over time with use. Unfortunately, things got worse - after a few weeks of use, the Shift key started to "stick" if bottomed out, really annoying, especially since this is one of the most used keys. I finally decided to completely take the keyboard apart and deal with it for good. After disassembling the keyboard I found out that the stabilizer would come into contact with a rubber standoff, which also had lubricant all over it. This was the cause of stickiness. Cleaning everything up, and reapplying a small dose of lubricant was all that was needed to get the Shift key to feel great. Forgetting all that - like I already stated - I'm super happy with the keyboard. It just shouldn't be necessary for me to take 2 hours out of my day to take apart, clean, and reassemble a new product to get it to work the way it should have worked right out of the box, just because someone was a bit overzealous.

Loving it!

Got it today, hands on my first mechanical keyboard and feels so good. And a lot of difference in day-to-day way of typing.

Excellent keyboard

I rate this keyboard 5/5. It is built solid, sturdy, heavy. It's weight plus the rubber feet keeps it stable. I think the S1 is much better than the K3 in both sound and tactile feel (both using red switches) which I previously owned which I gave to my wife who loves it very much. The sound is not annoying, very much reminiscent of old mechanical keyboards. I would definitely recommend this keyboard to my friends/colleagues.
