  • It heats my 20 gallon community tank
Size: 75W for 10-40 Gallon
This heater works well. I have it in a 20-gallon community plant with live plants, guppies, betta, cory catfish, and some shrimp. It's a great looking heater and it works like it should. It's also nice that you can set the temps manually as most are auto-set to a certain temp.

  • Great heater!
Size: 25W for 1-15 Gallon
I have a betta tank with a pre set heater. My betta was failing, the heater was only heating to 73°. I put this heater in last night, within a couple of hours the water was up to 78°. He is much better already. The heater is small enough for almost any tank, suction cups are strong, with a couple of extra ones in the box. The cord between the unit and the awesome digital control is more than adequate, as is the cord going to the plug. I feel better having the control instead of a pre set. The digital display is great. Can't beat this heater. ... show more

  • Consistent temperature
Overall, this is a pretty good tank heater. It suctions to the tank wall easily and has not come off at all since I put it on. It is very easy to adjust the temperature, but the temperature is not super accurate. It has been consistently 3 degrees off. Other than that, it has kept a consistent temperature without fluctuating, which is a much more important aspect than the degrees being a bit off, in my opinion. ... show more

  • Really accurate heater
Size: 25W for 1-15 Gallon
I was wary of this one because of the low number of reviews and the fact that the reviews that are here all got the item for free, but this is a legitimately good tank heater. I bought this one to replace a Pets Mart brand heater that stayed 6 degrees above target regularly. This one stays perfect almost to the degree confirmed with 2 different thermometers. Really impressive. Plus my betta likes sleeping on it, so it must be a very steady, consistent heat. ... show more

  • “Energy-Saving and Precise Temperature Control
Size: 75W for 10-40 Gallon
This aquarium heater has exceeded my expectations. It maintains the temperature with great precision, just as the seller promised, and its energy efficiency is remarkable. I decided to replace my previous heater, which consumed 50 W, with this model that only uses 25 W, helping me reduce energy consumption. Additionally, the material quality is excellent; it feels sturdy and durable. Without a doubt, a great purchase for those looking to save energy without compromising performance. ... show more

I’ve had mine on all day long and it can’t get the water up to 80 degrees F. Won’t even budge the water temp. Real big disappointment.
