    DO NOT BUY, PLEASE

    By Hardak1973 on Aug 21, 2021

    I bought heater from different store.. The heater does not work right. I have to unplug it after a couple of hours because it shoots the temp up to almost 86 degrees. For bettas, this is way too high. Regretting purchase. Please, do not put your fish through the stress, find a better heater that you can adjust to right temp.

    works good for a very short timeframe

    By Kaela on Jun 10, 2021

    Was great when we first bought it. Worked well enough to keep the bowl just warm enough. Our betta passed away 2 months ago so we didn’t use it for awhile l. However we got a new betta and now the heater doesn’t even work even tho it was only being actively used for a month total. It was great while it lasted but it definitely not a long term heater. You get what you pay for. Pros: warms up decent quickly, very small so fits in the smallest tank you could get, cheap but works Cons: only way to turn on is to plug it in, no indicator button so only way to know if it works is to actually put your hand on it, doesn’t last long at all If you need something in a bind this is for you, if you need Was great when we first bought it.

    Does Not Work!!!

    By Whitney on Jul 3, 2021

    I have two of these one for a 1.5 gal and one for a 2 gal tank neither of them work. They have no switch or light so you never can till if it is working and they never feel warm.

    Pretty good

    By Aiden on Jul 10, 2021

    It’s not perfect, but it gets the job done. The suction cup doesn’t really work, I ended up just taping it to the side of the aquarium.

    Amazing tank heater

    By 1111 on Mar 8, 2021

    This heater was perfect for my fishes tank- my old heater broke so i switched to this one. My fish, tsunami, loves it! Heats my 3.5 gallon tank perfectly- maintains water to 80 degrees perfectly. Arrived quickly too!

    Not doing its job

    By MarkT on Jan 13, 2021

    Have bad luck with Beta fish dying over winter months and hoped this would keep water temp @ 75 to 80 degree per Beta recommendations. Have 2 gallon tank and this heater is not warming water. Have heater for few weeks now and assumed may take week or two to keep water warm. Put finger in tank ever morning and water is very cold (feels like 60's). I scoop out large coffee cup of water ever morning, boil in microwave, and replace in tank, and this is only way can keep water warm enough for fish to survive.

    Excellent !

    By betaboo on Jan 4, 2021

    i have a 2.5 gallon with 1 beta, live plants, and a filter. This heater is excellent. I put it in and have hardly thought about it cause it works like a dream. Tank is kept warm and approximately 78 degrees. I live in a humid warm area so I don’t have to worry bout my outside temp getting too cold and this not heating enough but the extra lil 5 degrees it offers still helps tremendously in the winter. In the beginning it got a lil algae-y but i just swiped it with my fingers and it’s been fine since.

    Works just like it says

    By PittieMom on Jan 27, 2021

    I think the people claiming it doesn’t work might not be using it properly. There is no set temperature, but it heats the water to about 6 degrees higher than whatever the current temperature is. You have to let it sit, unplugged for at least 30 minutes in the water before you plug it in, then it will heat the water up to that temperature and keep it there. The people who said their water got up to 90 degrees probably had a starting water temperature of 84 degrees already or a very hot room. I use this is my 1.5 gallon desktop tank and it keeps the water at a steady 80 degrees for my betta.

    Lifesaver!....(Literally!)

    By Kylie on Jan 21, 2021

    I was very worried for my neon tetras before I got this heater! It keeps the tank at the right temperature at all times now! Works amazing and does wonders for my healthy fish! If they could talk, I know they would be telling me how thankful they are for it!
