good product fast shipping

Sturdy and stayed stuck on glass terrarium wall. Seems pretty accurate as they both matched up together before being placed in the terrariums. Placement for the sticky could be better or a permanent way of sticking as when the batteries need changed, it’ll have to come off, but that could also be a user error on my end. Overall recommend.

If these ever actually die or use up the extra batteries I will buy the same ones as replacements. Just replaced the batteries in one and I’ve been using them for 11 months now. The one with dead batteries has been working overtime. It’s in a basement. In Florida. On waterfront property. So it’s been reading 99% humidity the entire time. The poor little thing is probably as exhausted and overheated as I am! I still have one more set of batteries and the other meter is still going strong. I can’t think of the last $5 I spent that lasted as long as this pair of hygrometers! They are probably not accurate enough to conduct college thesis scientific experiments, but they are CLOSE. And that’s all I needed - to get an idea of how the humidity levels in the basement compared to the rest of the house and how those levels change with the seasons and rainfall. I think the humidity readings are more accurate than the temp readings, which sometimes showed ~4• off from the thermostat BUT my purposes are really for the humidity readings. Totally satisfied with this purchase and will buy same ones again if/when this pair quits or the batteries all die. Probably the extra batteries alone are worth the total cost. #battery life excellent #accuracy close enough #happy customer

They work well with a 1% variance in humidity between the two, the temp is matching on both. I got them to monitor the humidity of my guitar since I live in a very humid area. A spare set of batteries were included thankfully, because the ones included were low and after a couple of days the readings varied widely. But a battery change solved the issue. Im happy with my purchase.

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

I just wish there was an on/off switch!

Definitely worth the money you get two temperature/humidity gauges 4 sets of batteries and two velcro tapes. I am highly impressed both gauges were pretty much spot on and also were within 1 degree for temp and 1-2 points off humidity compared to my zoomed hydrometer. I want to note that the probe it is placed at the bottom of my gecko tank so there naturally would be a little bit of a discrepancy between the zoo med and the two aik tryee mini hydrometers. My zoo med hydrometer was about $10 this was half the price and you get 2 hydrometers plus extra batteries I wish I came across this earlier. I am happy with my purchase and will be purchasing more for my various reptile tanks.

very good though it did not my grandchild pull power :)

I think these are all made in one big factory in china, that said I ordered 2 and there was a 3 point difference in one of them, I did a hygrometer test ( google it) and figured out which one was off so I just add 3 to it and get the correct humidity. These are all a plus/or minus thing

Worked and lasted a while
