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: Very nice heater! - This heater is packaged nicely and works great so far. Seems to be accurate and comes with a stick on thermometer that is accurate and a hand held LCD thermometer. Pleasantly suprised with the quality at this price, hopefully it lasts me a while.

### ⭐⭐⭐⭐⭐ Reliable Heater That Keeps Perfect Temperature — Even in a Cold Garage
*by M***W on January 5, 2026*

I bought this aquatic heater for my red-eared slider turtle, and it has been working great. It keeps the water at a perfect, consistent temperature, which is extremely important for turtle health—especially since my turtle is currently housed in a cold garage. Despite the colder environment, the heater maintains the set temperature without any fluctuations. It feels well-built and durable, which is important in a turtle tank where equipment can get bumped around. Installation was easy, and once set, it requires very little maintenance. Overall, this heater has been reliable, efficient, and gives me peace of mind knowing my turtle stays warm even in a colder space. I’d definitely recommend it to anyone keeping a red-eared slider or other aquatic turtle.
