I expected the lower temperature on the ultratherm, although that is still too hot.

I did NOT expect that tiny, piddly 4W heat mat to hit 133 that fast.

I have their 40 gallon breeder size somewhere, I wonder if that one is as bad. If I find it, I'll test and just post the results here. It's something like 8"×11" I think.

I almost wish I had some of the other pet store brand ones. Like Zilla. But it isn't worth paying for that to test out.
