Nice little heater
**Update- this heater keeps a rock solid temperature and works well ina 5 gal tank. Fyi- before doing a water change, be sure to unplug it andafterwards give it 15-20 mins before plugging it back in. This will let theglass cover stabilize and minimize a change of it cracking. Good heater!!This is a pretty good small heater. This is smaller than a traditionalaquarium heater, and you can’t set the temperature as its preset.(I did buy the temp adjustable DaToo as a backup in case this one didn’twork out or happened to fail)I have found that it does not run at the stated 78 degrees, as the roomtemp seems to affect it. In a 5 gallon tank, with the room temp at76.4 degrees, the heater warms the water to 80.4 degrees and keeps itrock steady at that temp. It tends to cycle ON for 4 minutes, thenturn off for 12-13 mins. The red ‘ON’ LED is quite dim to see, thegreen OFF LED is a bit brighter, and the cord is on the short side.Am using for a Betta and so far so good, will be keeping an eye on itfor reliability and how accurate it maintains temp.Before this, I was using one of those constant-on 5-watt heaters,in a 2.5 gallon tank. It did a good job but tended to overheat thewater if left on constant. A work around was to use a electric outlettimer- set for 30mins on and 1hr off was able tomaintain a stable temp without overheating.

MINI AQUARIUM HEATER THAT WORKS
I have a large glass bowl that I use as an aquarium for my small tropical fish and I got this heater to use in it because it is only 2-3 gallons in size and this heater is perfect for it. It works great! I have purchased small heaters before and had trouble with them i.e. not really able to control the temperature well, but this one seems to be working great and keeping the temperature right at the correct level for my tropical fish without overheating the small tank. So I am happy with it. It came with a free stick on thermometer which didn’t actually work i.e. the temperature would not show on it so I pulled it off the side of the tank to throw it away and it left sticky residue on the outside of the tank which was difficult to remove. I think it was included so you could verify that it was keeping the temperature at the right level. So the small stick on temperature strip was a failure but using a regular thermometer in the tank shows that it is keeping the temperature at the correct level and the heater itself has a little indicator light which shows when the temperature is safe (green) and when it is too hot or cold (red) and that works. So I threw the temperature strip away because it did not work and with some difficulty I finally got it off the side of the tank. It left little sticky bits behind on the glass that I had to scrape off. But the little heater works great and has its own internal safety indicator light where red equals out of safe range and green means it is safe and that does work. But the external strip thermometer didn’t work and when I tried to remove it from the outside of the tank it was difficult to get the sticky adhesive off the side of the tank as some of it pulled off the little strip and stuck to the exterior of the tank glass and was difficult to remove from the glass. So I threw the small thermometer strip away as it was useless i.e. no temperature showed on the strip after a full day but the heater itself is great.

Great little heater
Great little heater for small tanks. Very durable and nicely built. Easy to use. Waterproof. Easy to clean. Color blends into back of aquarium or scape. Readability is accurate.

It does the job
The heater keeps my 3-gallon tank at a steady 78°F, and itâs really small, which is great. But it takes a while to heat up at first. Works fine once it gets going, but I expected faster warming.

Very nice mini heater
So far so good.. Our betta seems to love it I see him swimming and hovering all around it and he made a bubble nest above it.. so I take that as a positive. My daughter wanted a fish so I did the homework and bought all the necessary equipment and a heater was one of the things we needed for a betta fish. I have a 3 gallon tank to start off with so this mini heater was the size I needed but I was still a bit nervous because I didn’t want to cook our fish..so I set everything up and kept and eye on the temp for a couple of days before I actually bought our fish but it’s been true to what it says, it turns red when it’s heating and it turns green when it stops when it hits 78°F.. I’ve come to trust it but I still keep an eye on it just to be safe..all in all so far so good I’m satisfied with my purchase.

Works great the temp gage is hard to tell where itâs at. But heats the water well.

Perfect for my little betta, I am using it in a 1 gallon fishbowl with a filter and he is much healthier and more active in the past few weeks since I installed the heater.
