This has been an extreme help. My moms fish tank is close to a window and even though it isnt open the draft was making the tank cold and causing algea to grow fast. Getting this heater running was very simple. You plug it up and it automatically adjusts to the necessary tempature depending on the water. It has the green indicator to show its working and it warmed up the 2.5 gallon tank within a half hour. It stuck easily to the side of the tank and hasn't moved since.

I didn't have a fish tank heater before I bought this one and for our 5 gallon tank it's done a pretty good job! It's not too big or bulky so you don't really see it. It comes with a temperature sticker and it usually only keeps the tank about 76 degrees. It sticks to the plastic tank walls well and has 0 noise. Over all it was a good purchase for the price and our beta fish is happy.

Ordered this for my new betta, Sully. I had a heater before I bought this one that didn't keep the water at a consistent temperature. I decided to buy a different heater, and this one is great! It was cheaper and smaller, too. My only complaint is the suction cup wouldn't stick to the bottom of the tank which I wanted it to so I could bury it in the substrate. The heat does stay at a consistent temperature which I am very happy about. I love it! My betta will even swim up to it if he wants to be extra warm.

Works pretty good for the money! You simply place it in the tank, plug it in, and raised the water to its pre-set temperature. You can’t adjust temperature settings on it, but what do you expect for 5 bucks? Good for small tanks and fish bowls.

When I would clean my tank, obviously the water would change and part of the heater wasn't submerged while doing so. But unlike other heaters that shut off, this one stayed on and burned whatever it touched and even melted the plastic attachment that suctioned it to the tank wall. Very disappointed

This was a cheap unit and it sure functions as one. The suction cup got mucky and useless after the first water change (one month). When removed from water, instead of being a reasonable temperature, it automatically goes into high gear and burned the wash rag it was resting on while I was cleaning.Should I have unplugged it? Probably - but should a device that automatically heats steel coils up have an auto off or safety feature?You betcha.My fish is warm, wallet didn’t mind it, but it’s absolute junk.

It works great sticks to the side of the aquarium. Red light means it's heating green light means it's maintaining? Works great for our little tank. Also comes with a thermometer that you stick on the side of the aquarium.

I bought this expensive product for better care of my fishes & shrimp. Instead of maintaining the temperature, as advertised, it overheated the water killing everything in the tank. My beautiful planted tank was ruined. 👎ðŸ¼
