> 3 dayI had really high hopes for this product. It does a great job at doing what it needs to do the only issue I had with it was it doesnt stay on the tank at all! I have a chameleon, a bearded dragon and two leopard geckos, I had gotten some for all of them. The thermometers only stayed on for a few days before falling off, the adhesive it comes with is just not very strong. Other than that it worked great.

Greater than one weeknot the most accurate gauges ive ever used in my life but 2-3% off is close enough for my needs

08-06-2025The temperature seemed to be accurate as both indicated the same temperature, but the humidity readings varied by 2 +/- percentage points when sitting side by side. Still close enough for what I need. and a good price.

> 3 dayI use several of these to monitor humidity inside musical instrument cases. I occasionally check their calibration using hydrated potassium carbonate as a standard, and I have never found one more than one percent high or low. Allowing for the value of the four spare batteries if you bought them at a drugstore, the devices themselves are almost free!

11-06-2025I got this to go in my guitar case. I had alternately been over-humidifying and under-humidifying, neither of which was ideal. Where to mount it so that it wouldnt rattle around? I decided to wedge a piece of plastic from a notebook cover into the area near the storage box of the case. Then I used Velcro to attach the humidifier to the plastic, so that I could get if off to change the batteries. Good luck.

> 3 dayI bought 2 of the mini hygrometers and they are giving the same readout that I’m getting from my larger, costlier devices. The size is perfect for placement into mason jars. The additional included batteries were a nice bonus too! There are what appears to be clips on the side that I am unsure of how to use, but am happy with placing them either with the included double sided adhesive stickers, or simply standing/laying down.

> 3 dayMuch more accurate than the analog hygrometers that came with my humidors. Its nice to have two of them. I put them both in the same humidor, and they read the exact same. Then I moved them to different places in the same humidor, and they registered the difference in humidity in different spots. I then swapped places with them, and they each adjusted to the same readout the other had in the same spot. Very pleased.
