Great idea but very poor execution. Only for a short time and only used light and puzzle parts. When using a jigsaw, it stopped working. I thought that the battery needs to be charged, but it does not charge, it flashes as defective. After that I tried to separate the battery from the handle and weld it together. Something in the contactors is shorted (see photo). I'm trying to find a replacement so we can get a fair trial, we'll see what happens.
