Features

  • SUPER MINI SIZE This aquarium heater is SUPER SHORT in length might be the shortest heater in the market. It is only a bit more than HALF of the length comparing with the traditional fish heaters! The innovative super short length perfectly solves the headache of the fish keepers on the traditional aquarium heaters! Takes up less space, easy to hide, but in full power! Temperature range is 64-93F.
  • ACCURATE TEMPERATURE Thanks to the intelligent inverter technology, with the in-built chips the thermostat keeps the heater at a constant temperature at an accuracy of 1F, much more accurate than the traditional knob-controlled fish heaters. The thermostat shows 2 readings the current temperature and the set temperature very easy to operate.
  • DRY RUN / OVERHEATING PROTECTION Full consideration of safety. With the multiple protections this fish tank heater will stop working when the water level is lower than the minimum water level (DRY RUN PROTECTION) or when the water temperature exceeds 97F (OVERHEATING PROTECTION). You are free from cooking fish!
  • MEMORY FUNCTION The last setting is stored in the chips of the thermostat. In case of a power cut, when the power recovers the fish tank heater will follow the last setting.
  • MULTIPLE USES This fish tank heater can be used for both fresh and marine water. It can be not only used as an aquarium heater, but can also work a turtle heater, pet fountain heater, and plant seedling heater.

  • Died in less than 12 hours - Updated with new replacement heater
Size: 200W
*Update - To much of my surprise the manufacturer was very fast at reaching out and offering a replacement. Replacement heater arrived within a few days. Much faster than I ever expected. New heater seems to be working well and haven’t had any issues with the replacement one so far. I’m guessing it was just bad luck with a defect on the first one. Updating to 5 stars for now. *Original review (1 star) - I set this up on a new coral frag tank. During the initial warming of the water to 77 degrees it only made it to 67 degrees and died. No matter what I did it would not turn back on. I guess I am going back to the tried and true heaters instead of these cheap ones. If you care about your fish stay away and go a name brand heater. ... show more

  • Just set up the tank
Size: 50W
I love the size of this heater. I’m setting up my 10 gal tank so I don’t have much space and the size helps a lot. My water was like 60* when I put the heater in. In no time the water was at 75*.

  • Love this product and company
Size: 50W
After Amazon accidentally sent a used non functioning heater I was contacted by the seller and offered a replacement free of charge. New heater arrived promptly in official box with instructions. Digital component allows for fast easy temp setting . No more hit and miss with unreliable dials or preset heater’s which run too hot. Love this product and this company. ... show more

  • Stopped working
Size: 50W
****wanted to edit to add that the seller reached out to send me a replacement. So ill give 5 stars for great customer service and how well the heater was working and fit in my tank. Worked great for about 3 weeks. Then stopped. Tried troubleshooting it and doing everything the customer service person recommended and never got it working again ... show more

  • Good little heater
Size: 50W
The suction cups are amazing and work almost too well. I have two 5 gallon Betta tanks and one heater works great and keeps the temperature at a steady 80° but the other one is struggling to maintain 78°. I absolutely love the digital read out & is why I bought these heaters. They take up hardly any room and keep my Bettas warm. ... show more

  • Works great in my 5 gallon Betta tank (with filter)
Size: 50W
I’ve had this for about one month and seems to work well. I place it next to the filter as it helps to circulate the temperature throughout the 5 gallon tank. No issues with suction so far. I try to keep the temperature specific to Bettas from around 76-78 degrees. I imagine temperature range is different for other fish types. I did a lot of teasers and my Betta seems very happy. ... show more
