Ideal for my crested gecko. Previously was using those cheap eco terra analogue thermometers, then I got this and compared it to the cheap one and the cheap one was off by 10 degrees

I've been using this for a couple years in my chicken incubator. It is very accurate and dependable. I haven't even had to change the battery. I definitely would recommend this!

They work great, temp and humidity has been reliable, they are small which is good and accurate when compared to other measuring devices. I have 6 of them now for all the animals in our home that require them.

I’ve bought 4 of these so far for various enclosures and in 2 years I’ve never had to change a single battery or replace any of them. They work great and I love not having permanent adhesive ruining my glass enclosures. However, the suction cups really suck so I’ve taken to hanging them with medium transparent command hooks (the kind with the metal wire hooks).

This thermometer works perfectly just very bad suction for both. One of my suction cups on the humidity reader came bent in and never worked and other just wouldn’t stick. So I would recommend the product just come ready with suction cups.

Je suis un peu déçu, la résistance me semble légère, les données me semble un peu faussé , un peu gadget, à voir avec le temps

This little thermometer is convenient it has two separate probes for temperature and humidity readings which appear in big numbers on the screen. The screen is not readable in the dark though which is a bummer! I use this to keep track of humidity and temperature in my tank day and night, and having to flash my cellphone light to see what the thermometer screen is reading is a big draw back for me. I though the screen would be fluorescent or something like that. Besides this, I think it is a decent product the fact that the humidity probe is not waterproof is annoying too (I have to take it out of the tank every time I mist just to make sure I don't ruin it..) but this thermometer cost me less than $12, so I guess for the price that's what one gets...

Best thermometer/hygrometer you can get for this price. There are better, more accurate ones available, but they are often up in the $100 range.Have this set up in my bioactive gargoyle vivarium and so far it has been working great. Every time I mist, the humidity percent promptly goes up to 75-90% depending on how heavy of a mist, and then throughout the day will slowly drop back down to the 30-50% range as the vivarium dries out.Can’t ask much more than that honestly.Suction cups work too(unlike some of the other suction cups on this style thermometer/hygrometer)

I have two in my leopard gecko cage, one for both sides of the tank since the temps change between night and day. I will say that the auctions have been very annoying, but easy to fix. The first one I bought, the temp one didn’t want to stay, but eventually it did. My second one however, the temp/humidity reader didn’t want to stay. We eventually used tape to keep it in place. When they arrived, the suctions seemed to have been bent and shaped differently, which I believe is the cause of why they don’t stick as well. I’ve heard of people replacing the suctions, but they have to destroy the old ones to remove them and I have no idea how they put new ones on. Either or, still been a pleasant experience.
