Look, you get what you pay for, I get that. I was in a dilemma and needed a 2 1/2" hole saw. I saw the set and even though I have all the other sizes I was like what the heck. How bad can a $12 full set be? . For it didn't have to be great for the cut I needed. But my footage was supposed to be relatively light (HDF) and had issues. It's not very sharp and took a lot longer than I expected. Anyway, it did the job , but the results aren't very good I wouldn't use it on hardwoods or anywhere else where someone would actually see the hole it makes.
