I always trust CMT as should you. They are definitely not Forrest but cost a heck of a lot less too. I am not a cabinetmaker just an experienced carpenter and I am pleased with this blade.
I got 3 of these. One for my combo blade and 2 for my Freud box joint blade. The insert is a quick easy way to upgrade the cut of any saw and for the price it would be hard to justify making your own. Overall it works extremely well. It greatly reduced tearout on plywood and other difficult wood. The set screws easily adjust the plate so you get a nice flat surface. My only complaint is that on the General Int. 220 the insert flexes on the left hand side of the blade. This is seldom a concern but cutting small tenons on the left side of the blade could be a problem. The right side is much beefier and I haven't had any problem there. The up side is that the plastic is very slick and it is easy to push material over it.
If you don't have the time, or don't want to make your own this is a great general purpose insert. Get one for each blade.
