Heats wonderfully

Love this heater. Six months and going strong for my 50w. Heats my ten gallon easily. Just bought the 25w for my 5 gal, and the temp markings are a different color and harder to see, but it looks like it's working like a champ too.

Works extremely well, easily breakable though.

Works very well for my 5 gal with my betta fish, easy to use and maintain, it is very fragile and I broke my first one with a small tap by accident but I knew it was my fault so I bought a second one. Cord is a bit short so make sure your outlet is close to your tank but other than those two things I don't ever worry about my tank getting cold. Very happy.

Great buy

The item arrived quickly (and I needed it since my old one died unexpectedly). I’m very happy with my purchase and my fishies are very happy with their water temperature 👍🏻

Works, but temp is off.

Temp won't reach 82 in my betta 5.5 gallon breeder tank but does keep the water at 78 on full power so it keeps them comfy.

Easy Setup And Heats The Tank Perfectly

My fish loves it and it works great. Quick setup and you have a warm fish tank. Priced right too.

Good heater for my betta tank

My fish room is cold. My old heater could not keep up. Betta fish need a temp of 78-80°F. 6 gallon tank. Has no problem keeping it where it should be and is short enough to hide in the back.

Good combo, temp strip it spot on, heater works right

Keeps the temperature good. Don’t hook it up to your UPS if you use a battery backup for your tank, it sucks power. Fishies are happy in the balmy water.

Works as expected, price is right

Ordered two of these for two 2.5 gallon betta tanks. Both tanks have stayed a consistent 77-78 degrees for about 30 days so far.

This heater is by far the best I have used

I have used so many different types of heaters and everyone of them failed either cold or frying my fish . This heater is by far the best I have used . Ihave got 6 out of 7 fish tanks that are constantly at 78 degrees . This gets the tank on where it needs to be for temperature .

Fish like it hot

Seriously, this is what’s kept my fish from dropping like...Er, flies. I owe an apology to all the previous flies...Er, fish...
