I just came across this video ( https://www.youtube.com/watch?v=fk66IacfJ6o ) and these look really interesting. I often make cuts at regular angles and widths and to have specific inserts for the these tasks is appealing. Where I come from having these shipped would cost about $150AUD delivered including 2 inserts whereas genuine Sawstop inserts would cost about $90 AUD delivered. Replaceable inserts cost about $20AUD for a pack of 4 including ones to hold the riving knife, splitter and dado. Sounds like a much more cost effective way to go if you need about 5 or 6 inserts for particular tasks

Anyone got these and have an opinion on their durability and accuracy as well as how snugly they fit?
