Ingenious copy of the Festool Domino......only a lot cheaper

The Festool Domino 500 (the smaller unit) retails around $1400 here in Aus. So this home brew version certainly can save you money but is it as accurate, versatile and easy to see as the Festool unit????
I wonder if he used a CNC to cut his parts?
Cheers
