I think this review was too harsh too.
Connectivity issues aside (could be prototype board issue), I think this is a good keyboard choice in this price range.
I own a Keychron K8 and the Q1V2. The Q1 is their most premium build, and there is now a Q1 Pro which is wireless. I expect they will be adding "Pro" versions to the other models in the Q line. So it didn't really make sense to say the K8 Pro lacks gasket mounting because the Q series is their "upgrade" option if you want gasket mount. The K series is their budget wireless line, and it's been upgraded to be QMK/VIA and with more dampening, new keycaps, all worthy upgrades to justify "Pro". I know that "Pro" is often misused marketing term, but Keychron is not the first maker to do so. I have the regular K8, and definitely I feel it would worthwhile to pay a bit more for this K8 Pro for all the enhancements it offers over the regular model.
Also, you said the G Pro switches were unlubed, which is false. (

Lastly, I feel it's better to pay a few bucks to get the full kit over the barebones. The keycaps are fine IMO and Red switches are a good choice, so why not pay the $20 more? And another $10 gets you the aluminum frame version. Out of the box, I'm pretty sure most people will feel this to be a nice upgrade from their Razer or Logitechs.
