BbyBoa zoo med 500r. It hit a max inside the tub for 10 min of 160 then clicked off and it dropped to 85º then clicked back on again. On and off just like it was designed to the problem is the tape is too high a wattage, and at 100% power is simply too hot. It takes under 8 seconds to get to over 100ºF in the set up I was using.
Never used a ranco but at 79.99 hardly a good deal when the Herpstat is 109 and is on sale 10$ off...
