I just wanted to report that received my keyboard (104 bamboo) on Thursday, and after working on it all day Thursday, Friday and Sunday, and a good part of today, I couldn't be happier. The only real issue I had was that when I took off the plastic wrap 5 keys fell off. I was glad that I had already read about this issue, and after removing the 10 screws from the bottom, popping them back in everything has been fabulous with this board. I don't think I needed to take the bottom off, but I wanted to check all of the other switches to ensure they were properly seated.
I live in a very dry climate, which I think attributes to the fact that I'm not having any of the stuck keys that others are reporting. I also had no issues changing out the keycaps. I tried a few different variants, but ended up going back to the whites, I just like the look.
The number and variety of lighting modes was a pleasant surprise as well, and I just figured out a few minutes ago, accidentally while typing, that the color modes can be changed on every single one of the color options. The custom color mode is great, would be nice to be able to add different varieties of pulse to that as well, but at that point I think it would be easier to do with an app on the PC side to upload a new pattern/animation to the board.
I wasn't sure how I'd feel about not having n-key rollover, but I haven't found a game or a typing situation where I'll be hitting 6/7+ keys in the same row. I tried all of the keyboard tools I had, and while I can reproduce the reported issue, it's only in testing that it seems to matter.
Thanks @XMIT for all of your hard work putting this drop together. Comparing the board to the pictures of the original that you had, it even looks a lot cleaner in this release.
(p.s. I thought I ordered the lighter weight springs as well, but didn't receive them. I haven't been able to find the paperwork to show that, but if I do find it, I'll open a case with Massdrop)
Good luck everyone with your boards; the concept of Hall Effect that prompted me to buy the board in the first place, is still cool, and the implementation is excellent. Happy typing!
