Product review (5 stars): FINALLY!  One that works!!
Gaaaah!  I first bought an AccuRite magnetic which gave humidity readings 16, 21, 27 and 62 seemingly at random and with nothing in between so I knew that was wrong.  Bought another style of AccuRite, and it did the same thing but the two of them, side by side, never agreed even within the same range.  I saw this one on Amazon and took a chance, but I bought two because if these didn't agree, they would both go back.  If so, I have a backup.  Well, they agree!  And since, I also found my very old but accurate dial type which had gone MIA, and these are consistent with that.

I bake all our own bread, and do so via machine, so humidity is really important since you're not getting feedback from handling the dough.  These tell me right where the humidity level is, so I've had no misses.  I also make my own pasta, so again, a thing where humidity very important.

So this is a case where something priced low beats the heck out of another more well known brand that's priced higher.

Otherwise, it's a flip-out stand that's not super sturdy probably, but the bottom is flat as backup.  But either way, do put it in a place where it won't get knocked around (a trade-off I'm happy to make).  Also be aware that the little button battery that comes with it (1130 which can be bought cheap here on Amazon) is in the teensiest little ziplock known to man, so it's easy to miss seeing when you pull the unit itself out of its box.

Based on 2 out of 2 both working right, I do recommend this product.
