  1. Anas Bensaci (verified owner)

    A very nice board for those looking to try something in the 40% area. Very fun to build as well as it takes a bit of intricate soldering on the SMDs. Although I couldn’t get the reset button to fit in between the layers. It was constantly pushed in when I screwed the board together. So I removed it entirely, which isn’t a problem as long as you have a pair of tweezers to use when flashing.

    Regarding my previous review, Pete saw it and contacted me. He then sent all the correct parts so the keyboard is now flawless

    everything arrived according to descripion. The keyboard works perfectly. Building it wasn’t that complicated. it’s a very nice and particular build if you want to try something that differs from a more common layout.

    Just assembled my new board and I really like it! The translated japanese build guide was easy to follow and I am not an expert at soldering, so everyone should be able to solder this DIY kit 🙂 Some parts were missing but after contacting Pete he immediately sent them to me, nice service! Coming from a 65% keyboard it is still quite hard to use but very comfortable.

    Amazing shop, in EU. Nice board in 40% area. Great customer care.
    Coming from a 75% keyboard, now it is hard to use but very comfortable and funny to personalize it (QMK firmware).
