They work great, out of the 8 I got 6 seem very accurate and the other 2 are only 1 or 2% RH different. For my use and for this price quite acceptable. Only downside is that I didn't realize the batteries were already in use. I left them in the boxes until I needed them, only to find they worked all the time.
