I purchased several of these a couple years ago, they fit well, but as noted by other reviewers you can't use your splitter and gaurd when using these inserts. Plus if you cut a lot of dadoes, you need one for each size. About 6-8 months ago I discovered Betterly Tru Cut inserts. These are made from high quality machined aluminum, made to fit your saw. The blade section has a removable phenolic insert. While the main insert  cost's twice what the Leecraft does, you only buy it once. The phenolic inserts come two to a pkg and cost half what the Leecraft does, so if you need a lot of inserts, I do, then you come out money ahead with this system. The winning part of this system for me, was that you can still use your blade gaurd and splitter, as the insert is milled to fit your specific saw. Therefor it is grooved to accept the factory guard and splitter. It has enough adjustments on it to keep even the most [...] level nut happy and locks into the saw table with compression. It is very solid. The fit and finish are excellent. Changing inserts is a breeze and you don't have to go thru the leveling routine every time you change an insert. If you only need one insert then the Leecraft is probably a good deal, but if ya need more go with the Tru Cut.
