Nice tool but beware of the plastic threads on cap
The PRH2 is a handy tool and I've used it numerous times already in the short time I've had it to determine Wet bulb for calculation of target superheat. The size is just right and I keep it in my Veto TP4 when not in use. I wanted to give it 5 stars but the plastic threading of the cap and the unit don't seam to match very well. In fact if your not careful you can easily, very easily cross thread it. So be careful. I can get the cap to screw on but it's less than a full turn, which doesn't seem natural. If this cap wasn't able to be secured then it would be on its way back. So to summarize I really like this tool, it works well and it will remain in my bag.

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.

Temps
Excellent for taking wet / dry bulb temperatures

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.

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.
