Fantastic value and easy assembly. Just be aware: if you're using the Helios RP2040 microcontroller, check the pinout carefully before soldering. It has more pins than a Pro Micro so it is possible to misalign against the board headers if you're not paying attention!
I was little concerned ordering from this site seeing how there isn't many reviews. Throughout the site. However, came completely as advertised. They even shipped it out of the facility within the same day I ordered my kit. Very impressed by that. It does sit high and very flat when using the base board. Would recommend arm rest. I 3D printed a bottom plate to put mine on an angle and lower to the table.
Very minimalist kit which was easy to put together and inexpensive. Perfect for an electronics enthusiast who wants to try 40% without spending too much. The final height is a little high so I would recommend a wrist rest.
