The only flaw is the application of heat only to the perimeter of the mash. RIMS/HERMS works very well to keep the entire mash at an equal temp. Personally I think it's a waste of a nice big aluminum vessel. You'd be better off direct firing the mash tun and if getting a pump for RIMS/HERMS is a stumbling point, you can manually stir the mash when applying heat.
