Mini Hygrometer Thermometer 2PCS Mini Digital Humidity Gauge, AikTryee Hygrometer Indoor Humidity Monitor, Temperature Humidity Gauge Meter for Humidors, Greenhouse, Garden, Cellar, Closet, Etc

I use them in my humidor and they work great as a supplement to my analog one. They are always within a degree of each other so I am ok with the variance. They are so small so next I will add some velcro to the back and on the humidor so it can stay. I forsee alot of life from these and if not, they were cheap enough that I would buy again. Perfect for what they are made for.

temps and humidity not accurate and mounting method sucks but does an ok job for the price and general location. it should not cost that much!!!!!

I use these in my jars to monitor the humidity and it works for what it is but on the back where the battery enclosure is you push it down and slide it to open or close it and the it holds the battery in and pushes it against the connectors and if the door is loose the battery wont push against the connector enough resulting in the screen being faded its nothing serious I just used a little piece of tape and put it in the back side of the door to create more pressure, pushing the battery more against the battery terminal.

OK, I just received this but I am impressed with such a simple little thing. Yes, it is a basic humidifier, and for the most part just like any out there on the market, BUT what really got me, is what came with it. First, this is a packet of two for the same price as a single one I got the week before, but wait theres more. There is also two dbl sided velcro tapes, BUT WAIT the best part by far, they also included two sets of replacement batteries. Those damn little things can be expensive, but they sent two new packs (four in total). I know, its the simple things in life, but still, who does that. Most companies wont even through in the original set, batteries not included... OK done gushing. Overall, I am happy, and they seem to be as accurate as the single one that I am returning. Happy joy joy.

The thermostat is very good very accurate but the adhesive that it came with doesn’t last long and doesn’t come off. But overall the thermostat is good! :)

Both broke on day one. The little plastic piece that keeps the back on and the batteries in broke almost instantly.

I 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.

Seems to read fairly consistent between the two I ordered. Only had it for 3 months but havent had to replace the battery yet

I ordered the (2) pack of the hygrometer/temp gauges to use for each of my cars. I decided to test their accuracy against other digital weather gauges I have in my house and each other. I set the 2 up near the centralized weather unit for comparison and allowed them to stabilize for 3 days. I’ve supplied a photo of the comparisons. The reading differential to each other is 0.3 degree F. and 2%. The 2%, 40% & 42%, differential between each is not within the +/- 2% advertised. The hygrometer reading 40% vs. 39% of my home weather hygrometer is within tolerance and obviously the 42% is not with its sibling or the weather hygrometer. The temp on the two siblings vs. the weather gauge is within 3%. I ordered the gauges for my cars to analyze a dry cough I’ve been having that I believe is related to the humidity differential to exterior air and house air. The price of the (2) gauges are very inexpensive and are relatively accurate. The surprise was that the two sibling hygrometer units didn’t agree within advertised tolerance. I expected the siblings to be relatively close to the weather station and closer to each other. I didn’t measure the response time and accuracy, other than the 3 day stabilizing period. So the overall rating of 4 stars reflects the 3 star rating for the tolerance differential from the advertised +/- 2% tolerance between the sibling hygrometers. The unit is good general information of temp and humidity certainly for the price.

I place them side by side and they give different readings. I understand that there might be a small difference as the add says but not a significant difference in measures of humidity and temperature. So if you are looking for accuracy these are not it. I may return them.
