Only to complain about is the bit holder. The bits have not held securely and are partly simply dropped. But what is not the end, which was then simply exchanged for another. I do not know if this is a production error or not, is annoying in any case!
The metal drills are of normal quality. The service life is perfectly fine. The factory and clean ground. Even the countersink is to use and of normal quality.
The hardshell case is sturdy and well made. Includes clean and the tool stays in its place and not tumbles back and forth during transport.
I can not say anything about the wood drill. Drill not to test for fun somewhere a few holes into the wood around the drill so. But in appearance, there is nothing to complain about. The cut is in order!
A little tip:
I clean after use the stone and steel drill with a kitchen towel. Then I place a drop of oil and rub it with a soft cloth. Then hold the drill longer and set when not in use no rust on!
Very good price-performance ratio
