The tactile greys are VERY stiff. I type on a Model M and these far, far stiffer. This board is like lifting weights for your fingers. I'm enjoying them, though I've had to change my typing style to make sure wrists are floating and loose, fingers are curved even when reaching, and no bottoming out. Anything less than perfect form will cause muscle strain in no time. I have to relax to allow the natural weight of the floating hands do most of work in actuating each key. I've always been ham fisted and unable to avoid bottoming out and this board is curing me of this.

The tactile bump is not all that distinct, as mentioned by others. But it is there and I'll continue to get a better feel for it. The actuation point is high.

The build quality of the board seems solid. I haven't cracked it open yet. With the solid build of this board and these tight springs, this board is kind of beastly. It stands out from the other boards and I strangely find myself very intrigued by it's challenge.

The keycaps are shiny ABS. I prefer some texture so these will be changed. The stabilizers are Cherry.

Great build quality once I pulled it out of the box. The keyboard has a nice heft to it as I picked it up - as if I can knock someone out with it if I tried. This model was the only tactile greys available on a keyboard and was hesitant with the orange LED back light. After seeing it in person, I now prefer it over blue or green and maybe even white back light. Orange/red lights are a lot easier on the eyes at night (avid f.lux user) and during the day I can simply turn off the back lighting altogether. Oh yeah, I didn't find any documentation about how to turn on/off the lighting. Function f10 key toggles it. I didn't know until I read another review on this site on another KB keyboard model. That man is the real MVP for that tip. The key caps feel wank though. I want to replace them as soon as I find PBT set I like. My first experience with tactile greys after coming from cherry clears has been a bit underwhelming. The high actuation force of the greys heavily mask the tactile bump of the keys which made the clears appeal to me in the beginning. Don't get me wrong, I love the tactile greys! The added actuation force was much needed for me because I was taking my clears to pound town and bottoming them out at every keystroke. It'll take me a while to get to that level with these greys haha.

If you're coming from browns and want a more heavier key switch , I'd recommend going with clears over tactile greys. Clears still have that tactile bump with the feel of blacks as you bottom out. Clears are also my ideal key switch if you wanted a nice typing experience to go along with usability for gaming. Tactile greys are too stiff and now they basically feel like linear keys if I wasn't paying attention to the bump.

Build quality is good. Also the keyboard looks nice and was delivered with 2 extra keys (squirrel (esc), and apple (win)). I bought it because the activation force of the keys is similar to cherry green keys - which I like a lot - but without the clicky sound, so that I can use it in the office. The keys feel good and comfortable to type, although the tactile bump is not as clean and accurate as on the greens. If typing very fast the keys almost feel like linear keys which is a bit sad. Maybe I should try white switches next time.
