Just finished building mine after it arrived this morning.
I initially ordered a gray one, which (luckily) didn't pass QC. Sylvester then gave me the possibility to change the colour to black. Due to that the shipping took quite a bit longer than planned.
The white Mars box looks super nice, defenitely something I'm gonna keep, in case the board won't be standing on my desk all time. The pen also looks good, feels very worthy. Didn't get to try it yet.
One pcb works fine, though bootmapper client is kinda special to use for me... but it works. Still gotta test the second one.
My board is completely flawless without any dents or ano issues, just simple and nice black.
The diffuser sits very stiff, but I already removed and re-applied mine twice without breaking it.
One issue with it, though: The screws are about 1mm too long to use the board without the diffuser. Gonna fix that for me tomorrow, due to shortening the screws.
I have no idea why, but my screws are golden - I'm very impressed by that, looks better with brass plate and brass inlay than silver screws would do.
Right now I have no quality pictures due to bad lightening, but maybe I'll post some tomorrow.
Btw, weight is 3,45kg (7,6lb). I'm suuuper happy with this
e: On the second pcb, only 4 of the rgb leds are working. The others are red and won't change their color.
Sylvester, I don't really need a new pcb with them working, but how about a partial refund of the $40 for the second pcb?
