Very small and watch out for the welds of the buttons, the legs are not cut and protrude pcb, they are very sharp!

Très petit et attention aux soudures des boutons, les pattes ne sont pas coupées et dépassent des pcb, elles sont très pointues !

These boards look good and the keys have a nice positive click to them. The only improvement I would suggest is that solder pads are made available on both sides of the board for the SIL connector. Whilst the matrix works perfectly, it is awkward to solder a SIL connector so that this can be used on a breadboard. I would still be happy to purchase them again - even in their current format.

I didn't solder it in yet but the quality of the material looks good and everything as promised
