Review: Very tough and warm betta bed - Its a really good lil heater i bought it about 3 months ago and my betta loves sleeping on it for some reason. Also dw it wont burn your fish to a crisp bc like i said my betta likes sleeping on it instead of the plant leaves so if you have a betta with no place to sleep i suggest you put the heater as close to the surface as possible and make sure its still completely submerged like the instructions suggest and maybe your betta might like sleeping on it. Also when my idiot brother didnt take care of his betta about half the water evaporated outta the tank and he never topped it off so the heater was sticking out like a sore thumb so when i took his betta (bc hes so irresponsible) i actualy saw the heater was STILL WORKING! even tho it wasnt even in the water and it was still plugged in the wall all that time, it never even burned out or over heated. Pretty good lifespan considering it was halfway out of the water for about a month or 2 idk bc my idiot brother neglected the poor betta for who knows how long (Dw guys the betta is in safe hands and dw they arent sharing the same tank or even near each others tanks) I rate 5 stars for how long it lasted, its pretty cheap price and also that my betta thinks its very comfortable to sleep on. My betta loved it and even when i took my brothers betta i put together a new tank and let it cycle so while it did that i had to put his betta in a tupperware with that heater and i actualy caught his betta sleeping on the heater to so this is essentially a heater and a bed for bettas! ill put an image to show you my brothers previous tank with the heater in it to show you it was still working even tho it wasnt completely submerged for about a month or 2. Even if it breaks ill most likely buy another one from this seller bc of how cheap and hardy they are, it already lasted a couple months out of water so i doubt it will break anytime soon and my heater is already 4 months old and doing great so id say these are pretty good quality heater for the price they are selling for and also very comfortable for both of the bettas to sleep on bc of the plastic guard that wont cook them but rather keep them warm at night!
Review: Just what my 2 gallon tank needed. - Very reliable and kept the smaller tank at a perfect temperature. Great for betta fish!

## Questions & Answers

**Q: I have a hermit cab tank, can i used this for a tank that is not submerged in water?**
A: I would NOT. It is meant to be in water, and I think it would get too hot without water to disperse the heat.

**Q: Could you use this to take the chill off in a atrium?**
A: no, this must be completely under water and 150 watts is not going to have much impact on such a space.....better use 150 watt light bulb or more.

**Q: The included digital Thermometer did not include a battery. Does anyone know what # watch battery it requires?**
A: Mine did come with the battery, and "works". How accurate it is remains to be seen. I just received and installed the thermometer and heater tonight, so I'll check in the morning and compare to another thermometer.

**Q: Digital Thermometer supplied with this heater is almost 3°F off. Is there a way to calibrate it?**
A: Mine is 10 degrees off. I can not express how unhappy I am with this product. The dial on the top of the heater is nowhere near what the water temp is, and the digital thermometer they send with it is horrible.
Two other sources say they are off by 10 degrees. 
Never again....

Very reliable and kept the smaller tank at a perfect temperature. Great for betta fish!

### ⭐⭐⭐⭐ Good
*by R***Y on February 27, 2026*

Fine in the water, but when I originally turned it on I was filling up the tank and it got so hot so fast the plastic started warping and melting. I let it cool then put it in the water and that’s my fault it was out but wish it hadn’t warped like it did.
