No adjusting this Heater
I don't like that you can't adjust the temperature. It stays at 78 and my fish prefer 80-82. I wouldn't have purchased this Heater if they had put that somewhere clearly noticeable in the description. It's useless for the tank I bought it for but It's working out well in my shell dweller tank so I'm satisfied. Wouldn't buy another one though.Read full review...

IT DOESN’T WORK!!
I was glad that I finally bought this little heater for my betta fish but when I put it in the tank the light indicator is always showing me the green light and not red light. When I checked the temperature it’s always at 70• F. It would not go up! I’m really sad that this heater didn’t work out the way it’s supposed to. Now I gotta buy a new one smh.Read full review...

Works, but not perfect
The heater works well, but came without a suction cup, so it’s hard to keep it in the correct spot. I think that should have been listed differently in the description rather than “slight signs of previous use”.Read full review...

Nice little heater for small tank
Nice heater for a small quarantine tank. No adjustability, but does have a light display that lets you know if it's heating or has reached the optimum temp and is holding in there. Small and unobtrusive.Read full review...

Good Compact Heater
I've seen several reviews of this heater complaining of failures but i have not experienced the same. its been nothing but consistent and good. i currently have and use 8 of these and all of them work for me as expected. That's why I have eight. That being said; everyone should always remember its a mass produced machine and sometimes you can get a defect. Aquarium heater, washing machine, auto, batteries.....etc. I have a few more aquariums to set up and for the set & forget heaters I like these.Read full review...
