Every part of the process was amazing, from concept drawing to shipping everything was on par.
Installation instruction where good, my only 2 points are in the thermostat instruction it did not mention anything about what ohm setting to put it,(had to call tech support for that) second the wire that transition from the heated mat to the thermostat wire is big. Had to put down more tile glue thickness then what I would of used normally. Other then that over 1 year and still working fine.
