非常に小さく、ボタンの溶接に注意し、足は切断され、PCB突出していない、彼らは非常にシャープです!

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
