User Ratings and Reviews
5 Stars Good little heater
Has kept my tank in the betta comfort zone even when the room is rather cool.
1 Star Inconsistent and NOT SAFE to run dry
The heating is inconsistent between units. I had two 1- gallon beta fish bowls near each other, each with it’s own mini heater, and one was always much warmer than the other.
Also, one day I accidentally left the heaters out after the changing the water (oops), and they both melted within an hour, so they are not safe to operate unless submersed in water, contrary to the product’s description.
While small, the “flat” heater tends to curl and is difficult to disguise in a small bowl. The suction cup provided often came loose.
I am going to get larger bowls (2 gallons) and better water heaters. I do not recommend this product.
5 Stars My Betta Fish Love This Heater
I have read so many reviews about this heater. You just do not know what to believe. This is my experience. My Betta fish, Max is 2 years old and lives in a 2 gallon bowl and he loves the heater. My Betta fish, Piper is 5 months old and she lives in a 1 1/2 gallon bowl and loves the heater. My Betta fish, Zach who is almost 2 years old lives in a 1 gallon bowl (I swear he prefers a 1 gallon bowl to a 2 gallon bowl…he has been in both and seems happier in the 1 gallon) loves the heater too!
1 Star Great idea for little tanks
These little heaters are a good idea but mine were defective and cracked opened exposing the heating element and wires. The problem was handled swiftly and I will continue to do business with the seller.
5 Stars Great bargain, works
Bought this for less than $10. Keeps 2.5 gallon tank at around 80 degrees, perfect for my betta.
