I actually ordered only a spacer for a circular saw blade. The spacer work fine. No problems at all. My only issue with the spacer is that for the cost of it you should get three or four of them. I'm a retired machinist and you could crank these out a dime a dozen on a turret lathe. The charge what you do for one is criminal. With that said, the evolution saw blade that a friend of mine gave me, which I used the reducer bushing on to fit my circular saw worked fantastic. Spent the last 2 days installing vertical steel siding and I made a jig for cutting it on the 712 angle I needed and for straight 90° cuts. We ran that blade all day long for 2 days and it's still sharp enough to shave with 🤣.
