These have to be the least accurate things I have ever seen.

The rectangular one is accurate or accurate enough and has been what I used but I noticed files all had cutouts for these round hygrometers...

Well from my 6 pack 1 is within a margin of error to even be useful.

I get they aren't expensive but seems like a waste of money for this bad.

Just bought them after the realization of this. I will try to make sure I let you know as I found a really good deal that I'd be happy to share as well if they are good as long as you are fine with used.

ThermoPro TP39 and Inkbird ITH-10 After this thread the other day I bought some Inkbird's on sale from Amazon to test them out, have had some ThermoPro TP39 around (and outside) of the house, and one of the Inkbirds was about 5% above on a salt test in a bag, out of the bag, they are all, seemingly reading LOW. Little sick of this, so I bought a Protmex HT607 to test out to see if my feeling is right, that the only one of the hygrometers in the photo that's near correct (3%+/-) is the center ThermoPro. If my feeling is right, I'm going to return all the Inkbirds, and give ThermoPro some shit, make a warranty claim, where I'm sure they'll send me 3 more junk hygormeters. I'm not prepared to spend $800 on a scientific hygrometer that can only do push button spot readings, can continue to be amazed that the market hasn't produced an ADJUSTABLE always on moisture/humidity monitor. It's pretty maddening.
