I spent years looking for my heat limit. I got a bottle of Dave's and found my limit there, along with what a lot of you have said - heat for heat's sake, no flavor. After months of using a drop here, a drop there, and not enjoying it, I got tired of seeing the bottle mocking me in the fridge. I dumped it down the drain in the kitchen. Big. Mistake. The whole first floor of the house became an eye burn zone. Your eyes would start to burn in the garage. I "borrowed" a box of baking soda from a neighbor, and along with one I had, I did a series of a half box in the drain, plug and fill the sink, wait 10 minutes, drain the water, wait 10 minutes, start over. I did this 4 times before you could be in the house for more than 1 minute. The smell and the eye irritant lasted about 3 days. A word to the wise - put the bottle in a plastic bag and put that in the trash. Don't dump it down the drain. I still like hot food, but I no longer look for a limit. Tastes good? Burns a little? Works for me.
