I have a few questions,

The first is there a Canadian supplier I would like the chance to tinker with it.

Aaron, That is a tough test there. Did you run an open air test with the product on a hard surface with out something in direct contact? My tubs I have lifted 1/8 inch. I'd be very interested in this result.

My flexwatt the 11 inch hits 143º at 75º room temp uncovered. Too hot to be safe during a failure. The 17 inch flexwatt during the same only hit 88ºF I use it as a secondary heat source even if the primary fails and the fail safe fails it still never hits critical mass.

The connectors are quite elegant, much nicer. I am guessing if one felt so inclined the leads could be soldered to the rivet as well.

I have never been a bit fan of flexwatt it simply gets too hot for my tastes it just never felt 'safe'. I prefer the to see the use of lower wattage heaters there is no real need for a reptile heat appliance to get much over 100º-110º . I am very glad to see you all to take that to heart and also the commercial UTH some of them as well.

I have often wondered if it were possible to have a thermal decay patch built into to the carbon elements. That would melt down at the 130º mark to protect against shorts or thermal gain from contact. I suppose such a thing would be cost prohibitive? Perhaps built into the end of the cord close to the connector a thermal switch option. Just thinking out loud here.
