This is the best roller shutter bit set on the market. Setup was easy and all three cutters cut perfectly smooth profiles on the first and 151st cut. No more gluing fabric or drilling holes for wires. This set makes it easy to personalize pieces that are absolutely beautiful when assembled. The convertible door I created looked great and worked without getting stuck or getting out of line like traditional roller shutters always do. The only thing I don't like about it is that I didn't think of it first. I highly recommend anyone who wants a convertible door but never hassles to install an Amana roller shutter top. It was easy.
