Small and functional
Working great 👍. Looks sensitive so keep it safe, otherwise works great.

Accurate, feels cheaply made. Plastic not metal
Great tool, only reason for 4star is that I wish it was about one more inch longer for lined duct, and it should be made with metal, not plastic. Threads on protective cap are easily stripped. Measurements are accurate and as long as you have it in its own spot in your tool bag it should be ok.

Easy to use, nice size, not fragile.
Works great, needs several seconds to stabilize humidity and temp readings. The cap has not been as issue, it is plastic threads. If you don't cross thread the lug-nuts on a car, you won't have a problem with this unit. If you treat it like any other measuring instrument you have (don't drop it or treat it like a hand tool) it will last you quite a while. It has been used on several locations and been bouncing around the console of my truck with no issue to report.

Easy to use
Easy to use, and easier to read. Seems a quality product. The only complaint that I can think to have is the size. It is 3-4x the size around of a pen you would put in your pocket, and a little bit taller. I didn't take off a star because I had room for it in my tool bag, and it's small enough that room can easily be made in yours too. I'm happy with my purchase.

Good HVAC tool but fragile
I use this regularly in my work as an HVAC service tech. It calculates indoor wet bulb and outdoor dry bulb accurately to calculate superheat for checking or charging an AC system. It is a good working tool but it has its flaws: - it doesn't clip into a shirt pocket - it is too long. - it is somewhat fragile. Do not twist the top on too hard or the insides will rotate in the case and damage it. Don't drop it. I've broken 2 in 5 years but I'm hard on tools. - it can be slow to register temperatures.
