Makita drill and bit assortment

Have this bit and drill range for a year and am not as happy as I had imagined from Makita. There are nähmlich with me already all 3 small PZ2 bits which were present therein, moderate to heavy use, canceled. Furthermore, I can say that the magnetic bit is not the best, since the bits have it already repeatedly jammed. The existing drill have been dull even after a short time. However Peis for money is ok.
