I had bought it for 22-23 euros, thinking how bad it could be, at worst I could buy a 10 euro Stanley knife and make it work.

A The opening of the knife was crooked, but I fixed it with a file and patience.
B The lever that adjusts the planing depth is dysfunctional, poorly designed and poorly installed. Many times it stops working before even getting the job done, I haven't been able to fix it...
C It has distorted the chipbreaker at the point where the lever comes into contact with it.
D The chipbreaker was a disaster, it took 2-3 hours of filing to make it work...
E I replaced the blade with a Stanley one, its own blade was useless.
F The frog is a disaster... crooked, I didn't even bother with it...
G The cast iron parts are poorly made.
H The lever that adjusts the lateral movement of the blade, if used more than 2-3 times, starts pulling the knife up and it doesn't cut.

Okay, in a cheap construction, I won't mention aesthetics like the handles, etc., it was expected. However, in order for it to work, I can't imagine how many hours I have spent on research and filing... and it still doesn't function properly. Now I see that I have spent over 50 euros on it... I don't believe it's worth even 15...
