I can't tell you honestly but it won't be long it seems.

I passed one this morning (visual) and once I heated the clean urine and put it in the Wizzinator, it registered 106+. I let it sit in my floor for 20 minutes while eating and it dropped to 98. It eventually dropped to 96 and I put my hot hands on it and it went to 98 and stayed constant for 30 minutes.

So, if you are worried about temp then you have to hit it b/w 96-98 degrees or it's going to automatically fail you. There is no reason for it to be anywhere else.

To be safe, grab a thermometer, and a hot hands.
