I'm an electrician so I've used a lot of hole saw sets. I buy a lot of Irwin tools for work. I ordered this set because Revain makes it convenient to ship the product directly to me. I work in remote locations so I can't go to big department stores to buy tools. It's a decent kit, it has extra pilot bits which is nice and they cut great. The case is a hard soft case with a foam interior that holds the hole saws. This makes the setup compact, which is nice. Not sure how this case will hold up to heavy use over a period of time, it has a zip closure which hasn't let me down yet. The only downside to these hole saws is that the slots on the sides of the hole saws that you use to remove the "plug" are very small. This makes cleaning the hole saw difficult. I wonder why the Irwin designers didn't see this, all other manufacturers provide a large hole or slot. This is a big part of crown surgery, removing the cork. A good price for a layman. For a pro, that helps.
