TC-That's the exact set I bought. I could believe it. Only a 1/4 turn with the wratchet and BLAM! I couldn't believe how poor the casting was.
On the flip side, I've had good luck with their air tools. Die grinder, cut off saw, right angle grinder. I've had a set of uni-bits for about 5 years. Use them all the time, not dull yet.
