This actually works really well!
I purchased this fan with reluctance for a 3âx3âx2âcage with Whites Tree Frogs. I was having trouble with both temperature and humidity (both to high) To my surprise it did the trick for the most part. You can set where you want the temp and humidity to be and the fan runs automatically until both your settings are satisfied. In the hottest days we had it actually brought both numbers down. It took some time, 24 to 36 hours but it did work and I continue to use them and during normal summer temps. The humidity was the most important part because these frogs can get sick or die with humidity over 50%. Some say 30% and others say 50%, I use 50%. Finally, they are quiet!! I actually need to walk up to the tank to hear them running. I also double checked that my settings and the actual temperature and humidity were the same. I have an Engbird temp and humidity sensor that matches the readings I get from the fans. These were worth every penny I paid for them, and they might do better in a smaller cage. If your having temp or humidity problems try these, you wonât be sorry. Be sure you order auto on off as some are sold without this feature. That all look alike!

Good For Circulating Air In A Tank
I hung them in my lizards tank to get the airflow moving more. It was easy to use and quality seems to be decent. Fan level is a little louder unless you put it full blast then it gets quieter. It does seem like a stable option for airflow and functions well just fans a little loud but overall, a good product.

Effective and quiet
Bought these for my gecko. His enclosure got too damp and water logged so we needed to dry the soil out a bit but we also needed to keep misting it since he only drinks water from the mist on the leaves. For the first 48 hours, we just scooped the wet substrate into a spare tank and put these on high to dry it out quickly. Voila, good as new! Then we were able to put the soil back in his cage and put the fans on his enclosure to keep air circulating so that it didnât get boggy again.I like that they are quiet enough that I donât have any worry about putting next to my lil gecko. The flow is adjustable and can be pretty strong, certainly enough for his enclosure which is about 2x2x3 feet with glass walls and a screen top. One thing I wish I had known is that the fans have to be used as a pair. The first fan plugs into the power source and can be used alone. The second fan only plugs into the first fan via a little power relay, and cannot be used independently. I was hoping I could split up the pair and use them on two separate cages and thatâs not an option. You can use one or both, but not two as individual items. Still, itâs a good value.

Great Fan with Accurate Display â Just a Heads-Up on longevity –
The Reptile Ventilation Fan with Hygrometer & Temperature Display works really well and gives precise readings. The fan is powerful and perfect for keeping my reptile enclosure well ventilated.Just a heads-up â It works well for a few weeks then the humidity sensor goes haywire. It was stuck at 55% one day which i found to be inaccurate due to the fact i have another mechanical humidity reader it was on the low side at around 70%so i turned on my humidifier until it read 95% which is where i like to keep my humidity a couple days later it was stuck at 99 all day all night causing the fans to kick on and my humidity dropped to 50%This is the second sensor that i have replacedI will say this works really well for lets say dry tanks but for tropical tanks where theres water involved i do not recommend this at all if the sensor is exposed to water even just from the humidity humidifier itself it will stop working

So far so good.
I have had these running for a couple of months now and so far they work excellent. I barely hear them at all and I had no issues setting them up. For me it was worth the purchase.
