Works great!
Size: 50W
Works great to keep my bettas tank warm for him. Haven’t had any issues. I like that you are able to set the temperature and it shows you what temperature the tank is.

Nice little heater
Size: 50W
I have a 50w heater in a 5 gallon tank. I love that it has an external control for the temperature and it also is a thermometer. In addition to the thermometer on the heater, I also have a thermometer that mounts on the aquarium glass. The two are very close, within a couple of degrees. The best thing about this is I don't have to put my hands in the water to set the temperature and it's one of the few small heaters that doesn't have a 78° preset. It only has one section cup but it only needs that one. Instructions are clear, very easy to set the temperature ... show more

For my 5.5 gallon fish tank
Size: 50W
I keep my 5.5 gallon tank at about 74°F. Heater works really well but the thermostat doesn't work. The heater always says it's about 6 degrees lower in the tank than what it actually is. I use a separate thermometer to check the temperature daily. Because the thermostat doesn't work I also have to unplug it if my house gets too hot or turn the heater up if my house is too cold. ... show more

Over heated and cooked all my fish
Size: 50W
I was at first happy with this product. The price was good, the size was good it was working good. Then over the past weekend (I have only had it for a month or two), it went haywire and heated my tank up to 96 degrees F and cooked all of my fish. I am so mad about this. The temp is still set to 70F but nope it sure in heck didn't stay at it. The fish I had weren't cheap either and I had to order them from online and shipped to me. DO NOT BUY THIS. I repeat DO NOT BUY THIS. I have never written a review for a product but for this I will as this is just unacceptable. ... show more

running 2 of these in a couple small tanks, works great
Size: 50W
I have been using common big named store brand heaters for years and only seem to get a couple years out of them at best. Got one of these guys as a replacement and I love it. Setting the temp is easy and the digital display is great, helps watch temps compared to temp gauge. Purchased a second one now and planing larger ones for other tanks when needed. ... show more

Compact, accurate, and the built-in thermometer is great
Size: 50W
I got the 50W for a ~4 gallon tank. I had tried other heaters and prefer this one. I appreciate the very small size, and the built-in external thermostat which provides some peace-of-mind and means I don't need to add another piece of equipment (a thermometer) to a small tank.

Bad Suction
Size: 50W
The suctions is terrible. Just a bit after installing it fell and completely broke, glass shattered all over the tank as well as the black powder inside. Luckily, the fish wasn't inside yet. I do not recommend using the suction included because it works horribly .
