Surprisingly, these seem to be accurate. I bought several of two different brands (this brand, plus a more expensive better brand) to compare them to each other, to see if all of them had the same readings, figuring I would keep that ones that matched and throw away the outliers. But all of them showed nearly identical readings, once out of their packages and allowed a half hour or so to acclimate to the house humidity levels. So either they're all accurate, or all wrong by the same amount (the latter seems unlikely). These are small enough to easily fit inside a musical instrument case, to keep track of humidity levels inside the case.

I bought two packs and all four meters seem to be stuck at 60% even when set directly on a humidifier. If you shake them a little the needle may change a percent or two.

Nice unit. Seems to work well. Not as solid of construction as I thought it would be. But good value and works.
