I bought this set a few weeks ago after searching the internet for a suitable household saw. The set itself is great, I like that you can quickly remove the house saw. Cons: One of the 5/8 hole saws can't go all the way through due to the size of the mandrel. Because of this, you may need to use a hole saw on both sides to go through anything wider than about three inches. Also, there doesn't seem to be any extensions in the set. So if your distance doesn't allow your drill to get too close, you may need another set of hole saws with an extension.
