Received the keypad today (Cherry MX Red switches) and I've been playing with it for around an hour or so. It's not much of a review but hopefully it would help a little.
There was something wrong with the shipping at first but it was actually resolved quite quickly and thnikk threw in extra keycaps, which I thought was a really nice gesture.
Everything was alright, nothing got wrecked from the shipping and everything was in good condition. It only took me a minute to start. The only thing was that the keypad was so light, so it started moving around everywhere when I was playing with it. I'm not sure if it's not supposed to come with the tape or anything, but I found an alternative solution (?) that stopped it from moving around since my streamings are quite... intense.
The O-rings were completely fine too. It actually reduces the noise significantly and it's much easier to press down on the keys. This might be personal preference though, but I thought it would be good to just touch on it a little.
It's been an hour or so and everything's going good. There's no delay when I'm playing and I'm loving this keypad a lot! I'll update if there's any issues but honestly, I doubt there would be any. I wouldn't be able to show any live play or any pro plays since I'm only 13k but if a replay would help, I'll gladly contribute.
tl;dr 10/10 just go and get it already
