Finally had some time to build this one.
It is nice, I mean a lot nicer than other keebs I used. It has a lot of flex - flex cuts on pcb, leaf mount, rubber "gromets" on contact with case - it all makes it feel so soft when typing.
I'm not fuzzed about flex etc don't know if it make huge difference, but definitely feels softer than keyboards with top mount, without plate.
Its alu case makes it feel heavier than plastic cases, but not as heavy as for example Frog TKL or Rama U80. I actually prefer this weight, as U80 was too heavy for me - apparently I move my keyboard around on the desk and when I do that, weight makes difference.
I picked this grey case, but I guess other colors are also nice. I may pick up Lite version when its out, cause I like the plastic keyboards ( I may go with some funky color like that retro blue or purple). Build quality is great, no issues, no defects. Everything, from case to pcb plate etc - all looks good, well made, doesn't say cheap at all.
I built it with my 78g Zealios v2 and some latest MT3 Godspeed caps. Feels great.
I did not use switch foam or that tape mod sticker, wanted to see how it sounds without those.
It feels great, very soft, sounds REALLY thocky, no echo in case, no hallow sounds. To me, it sounds and feels better than Frog. Really.
It feels close to kbd67lite - that mount works well.
As it is hotswap, I have a feeling that switches get pushed too easily, when changing caps, I may be pulling them with switches, if you know what I mean.
If they release solderable pcb for this keyboard, I may get one and solder those Zealios.
Then get one more pcb for some linear switches - I've been toying with idea of getting Lavenders.
So, I would say - if you liked Frog, but want to try a lot softer mount, hot swap and about 800g lighter case, this is an excellent keyboard. I 100% recommend it.
