Review on 201-Piece T.K.Excellent Blue Conical Plastic Anchor Set with Self Tapping Screw & Masonry Drill Bit by Brad Laverentz

What a pain. This is my first time drilling a concrete wall and using anchors. I tried to hammer them in and the holes ended up closing up and I couldn't get the screw in. Turns out they put a 3/16 bit in it and not the 1/4 bit it was supposed to come with. I messed up my project time and was alone waiting/paying for the right size bit and everything else worked fine. The return date has long passed, otherwise I would have sent it back. Be sure to check the size of the drill bit before drilling.
