at times they are WELL WORTH THE MONEY in lowering the time and effort required in diagnoseing problems, and yeah! you do get what you PAID FOR in the better models

I use it for so many things but first got it for track temp. AC vents is another.

Heck, I've used them just about forever to track the temps in the animal buildings. They are great for doing spot checks for hot or cool spots in a building.
