Who gave more than 1 star has not used the bits, no idea of the craft or paid for the review !!!
Must have put on the drywall work often now and although you have to get out quickly with a normal cordless screwdriver with ordinary bits how screwed the bolts perfectly, I thought one probably is quite nice to have such bits. Did you happen to see at the hardware store, but there were only still PZ2 what I need.
Fact: The screws look despite perfect rectangular screw slightly from the wall. Who wants to filling then can forget that. Should it put no value and only fasten wood panels or the like can be the bits still in the bin to throw because the bit after 5 screw through the overturn is pretty abgegnaddelt.
