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!

Great little inexpensive heater. I added this to a small 2.5 gallon shrimp tank and it's working great. No manual adjustment, which is fine. I will say it does struggle sometimes on incredibly cold days (it's in the basement and it's in a room that has the door shut 24/7 and no heat supply, so its always about 60 degrees ambient in the winter) but by that, i mean it might drop to 76 degrees or so for a few minutes. The compact size and clean, simple aesthetic is what really made me choose this one specifically, and I don't regret it. I will definitely buy another of these next time I'm in need for a small heater.

It’s been seven months since I’ve bought this heater it’s had been keeping the temperature pretty good and it even tho it does hover at 72-73.5 degrees Fahrenheit I have this way because my dojo pond loach’s have to have water below 80 degrees Fahrenheit or they will experience fungal infections and ich infections there a cold water fish used to cooler temperatures somewhat similar to gold fish which are actually a cold water fish and I have a albino mini pleco algae eater some people would call it measuring in at 5 inches last time I checked and the pleco’s like temperatures in the early 70’s and early 80’s 72-82 degrees Fahrenheit is a lil bit warmer but not too much so 72 is the appropriate temperature and the Cory’s like warmer temperatures as well hovering in at early 70’s to the early 80’s 72-82 degrees Fahrenheit so to keep everyone happy or at least satisfied I keep it at 72 degrees Fahrenheit and even this it does go up a few degrees that’s fine as long as it doesn’t go below past 79 degrees Fahrenheit that fine but let’s get into the heart of the subject:how long will this cheap heater last?🤔 well for the last seven months it’s held up pretty well so I’ll eyeball it five eight years approximately not sure like I said “eyeballing” it.subject2safety well it’s hasn’t made my tank become a boiling pot of loach food so that’s a plus and it hasn’t burnt up,melted, exploded,glass or heater either or shattered,hasn’t,stopped working,cord or heater electrocuted the fish and hasn’t busted the tank which is 35 gallon bowfront aquarium to pieces like a ticking time bomb and thickness of this cheap heater well it seems to be the last time I put it in and also had felt it which I touched it because I was trying to see if it was working yes it is still working and I have three thermometers on the tank one inside of the tank and reads the temperature outside the tank it’s the one that it comes with and this is not gonna blow up in my hands or fish tank question NO it’s not gonna be so cheap that’s it’s gonna be like a cracker this if you ask me is 4th or 5th in the top five list of best heaters on the aquariumist market 1st being eheim 2nd fluval 3rd being probably United because I searched it up and so….any way fourth being I guess yes orlushy brand and fifth I guess because my mother’s tetra fish heater didn’t stop working or melt I’ll put Tetra in at 5th place because well that’s what I’ve SOMEWHAT have experience on anyway great heater highly recommended and will be buying another one of this or another variant if this brand this brand has really surprised me yet….but for now yes great heater Godbless!

I purchased 2 of these 1 year ago. I had a 20 gallon tank. The heater worked perfectly in that tank and maintained a steady temperature according to the supplied thermometer. I had to set the dial a few degrees lower than I wanted to get the temperature right. The 2nd was backup in case this one failed but I ended up with a smaller 10 gallon tank. This tank was in a room with wildly fluctuating temperatures from day to night. I ended up using this second to keep the temp from dropping below 72 degrees at night. I had snails and 2 small gold fish in this tank over the winter. It was set on the lowest setting and did the job. Last month I upgraded to a 29 gallon tank and I am still using the heater. At this point I noticed the heat on indicator light does not come on with small adjustments. I discovered the supplied thermometers are probably not even close to being accurate. They differ from 2 to 4 degrees from each other and the meat thermometer I used to double check the temperature. I will keep an eye on it. The other heater continues to work well enough. I will probably order another back up, they just don’t make things like they use to. 🙄
