Mine arrived. I put the keys on a TKL to see how they were.
https://imgur.com/a/umVgPYc3 things to note, with the disclaimer that the switches aren't perfectly straight so a bit of the twisting is on me.
1. the snowflake key on F5 is a teensy bit darker than the other novs at F6-F8 which should be the same color. the keys are photographed twice with the board turned 180 degrees so you can tell it's not the lighting.
2. the alignment issues noted by catbus seem to be here too, maybe not as bad?
3. See the homing bars? That it looks like there's not enough color by them? Yeah, thats real.
The good: this is the first time I've ever tried KAT. I like the profile and sound. The novs are sharp and the alignment there seems fine. My bars aren't crooked from 7u to 2.25u, at least not more than 2019 gmk sets.
I have...7? more KAT base kits in GB. I haven't asked for refunds and probably wont. The quality is worse than JTK years ago and people tell me they've gotten better and the pics seem to reflect that. If someone wanted to bet me their 1000 to my 100 USD that by the close of 2023 I'd have those 7 sets with this quality being the floor and that Keyreactive wouldn't fold, I'd probably bet it as insurance.
If there's something more you want to see, lemme know. If you said you had issues.........post. them. You have a phone w a camera and imgur's free. People make informed decisions based on these.
