So far its working pretty well for me....... I got the flex watt and ranco thermostat the other day and wired/setup everything and its working fairly well the only thing i will change soon is that i will put foil sheets under the tape b4 it gets taped down to keep valuable heat from dropping thru the rack.....cause so far I cant get the temps over 73ish(the thermostat is set for 100 with a temp difference of like 2) on the warm side(no pythons yet so no worrys) but ima try and do this fairly soon so I can start adding all the items to the tubs........its actually better than i expected so far and way lighter than melamine.
