Even before use the ball bearing on one router is stuck. Also the the wooden box was broken from the inside.
All in all the impression is bad quality, and somewhat pricey, the 3 piece router bits.
I try to contact service for a return.but the return form demands I attach some file, no explanation what file ?
On other occasions it was easy to contact costumer service, and all was working well, but for this return, I am unable to get through.
