Does NOT work immediately after installation

Arrived today, I opened the box and placed in my painted turtle habitat in the water and does not work as described. The "button" doesn't let you set the temperature at all, and if you don't even touch the temperature button, the numbers keep increasing on their own, and there's no way to stop this or set the temperature you want. It doesn't adjust from 92 degrees which is VERY hot to hold water. Beware! DO NOT BUY!

Pros
  • Automatic constant temperature function. Thanks to the thermostat's internal intelligent heating system, the aquarium heater will automatically heat up once the water temperature drops below the set temperature and stop heating once it reaches the set temperature. In addition, it has additional protection against high temperatures, so you no longer have to worry about scalding the fish.
Cons
  • No Instructions

This is the small aquarium thermometer you are looking for!

I dared this thermometer and was NOT disappointed! It works exactly as expected in my 3 gallon betta tank. I set the temp and it came up to temp and HOLDS the water at that temp. I have an analog thermometer on a suction cup in the front opposite corner, as far away from it as possible, and the temperature it registers is worth the money. I'll most likely be getting another one for my kids' aquariums as winter approaches to keep their fish friends warm.

Pros
  • External temperature touch controller. It is very easy to adjust the temperature with an external touch controller without taking the heater out of the water, much safer than before. And the dual real-time temperature display on the heating element and external controller makes it easy to monitor the water temperature.
Cons
  • Questionable purchase for the elderly

So far so good

I was afraid to try this because there aren't any reviews for it, but it seemed like my only option for a tank heater with a working internal thermostat that would fit my tank size (1.5 gallons). Pros: • It fits in my small tank • You can set the desired temperature • The shut off function seems to work, it only went 0.4 degrees higher than I set so overheating hasn't bothered me so far • Suction cups hold up well • Heater burns not and doesn't feel too hot • the fish doesn't seem to mind at…

Pros
  • Protection against dry fire and lack of water. This aquarium immersion heater is more sensitive and intelligent to protect against dry running and water shortage than other heaters. And it will turn off automatically when taken out of the water and the external controller will display the error code "E1".
Cons
  • Not sure
