For me, it's a bidet toilet seat. I bought one that didn't really fit as well as I hoped, so now I am shopping for a v2 based on experience. I don't want to live without one going forward. That's for sure.
No. I haven't cared as much about that and I'm not sure why. I've both learned the old fashioned way and haven't minded the results. I very rarely get the internal temperature wrong enough to not enjoy the food.
Pretty sure he means the surface temp of where he’s about to put the food to cook.
Use the laser to see how hot the cast iron is before putting the meat on. Or how hot the oil is before deep frying. The laser thermometers are good for that.
