User Ratings and Reviews

5 Stars Great bargain, works
Bought this for less than $10. Keeps 2.5 gallon tank at around 80 degrees, perfect for my betta.

5 Stars Good little heater
Has kept my tank in the betta comfort zone even when the room is rather cool.

5 Stars small heaters
I bought two of these heaters for my betta tanks. At first I was afraid that they’d be too hot because they are recommended for 2-5 gallon tanks, and my betta tanks are 1 and 1.5 gallons respectively. However these work great. It gets very cold in the room where the fish are and the thermometer could barely register the temperature (my thermometers stop at 64F). After I put the heaters in, the smaller tank went up to 78F and the larger tank to 71F. I’m happy and, more importantly, the fish are happy.

5 Stars Hydor mini-heater-7.5 watts
This is an excellent heater, goes under the marbles of my 5 gallon hexagon tank, keeps tank at warm level of 77 degrees, my Betta and ghost shrimp are very happy and thriving in the tank, couldn’t be happier with this hetaer, it is perfect for any small tank to keep warm, as long as it is 5 gallons or less, maybe even work for a 7 or 8 gallon tank. You will not be disappointed if you get this heater for a small tank or bowl, highly recommended.

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!

4 Stars It does what it’s supposed to do!
I purchased this little heater for a five gallon glass tank which housed a single male betta. It worked very well in the winter, keeping the water temperature around the low to mid seventies in a house where the thermostat was set at 68 degrees. That’s pretty much what the product description said it should do, so I’m happy. It’s a simple, unobtrusive little heating pad that you can place either under or on top of the gravel in your aquarium. There are no other bells or whistles like temperature controls, and it probably won’t do much for a larger tank. For a small tank, however, it’s great.

1 Star Cold Heater
This product you would think does what it says but it doesn’t. It’s a heater yet the water (i have a 2 gallon bowl with a betta fish) is the same temperature (room temperature) that I had without this extra thing that uses electricity.

I would not bother with this item. It’s supposed to be good up to 10 gallons heating the water, yet I have a 2 gallon bowl that it can’t even seem to heat up like it should.

5 Stars Works great for Bettas
I bought this item for my betta Carlos who was too cold in my house in the winter here in Michigan. I put him in a 1 gallon jar and put the heater unter the gravel. His water temp before was room temp which is 70 daytime and 60 at night. This heater keeps him at between 75 and 82. He is much happier and active. I would highly recommend this heater as many bettas die in the winter from being in water that is too cold for them.

5 Stars perfect!
My African Dwarf frog is in a 2.5 gallon glass bowl with a piece of black paper behind, making this heater and its cord practically invisible. It’s so efficient that I had to put it on a timer, as it raises the bowl temp by ten degrees in less than two hours. It’s sturdy, safe and takes up very little space. I will buy another one of these for my second frog tank.

I use one of these in each of my aerogardens because I keep my house quite cool. Works wonders on the veg crops!

I have been using this product in my tank for about a month now, and it has kept the water temperature at a steady 75 degrees. I have had no problems with the product. It is doing exactly what it is supposed to.
