Thought I would buy two of these since price was good. I never write reviews but came back to save someone some money. 1st one stopped working after 2 months and 2nd one stopped working after 3 months.
Purchased 4 of them to use in a 240 gallon tank, with in 45 days all 4 have stopped working. The lights light up fine, but they no longer heat up.
Bought this heater in Jan. 2022 and has been working fine. Now it will not get to set temp. The lights are still flashing to set temp. but temp has not changed. Set to 76 deg. but the tank temp. is still 66 deg. in my 55 gal.
I have had an aquatop glass heater in my tank that I had to replace at least 3x due to issues. This new heater from Cobalt has been such an improvement!!! Definitely worth the buy although I want to try the NeoPro heater next!
Love this new electronic heater! Heats my 55-gallon marine aquarium to 76 perfectly! Great customer service!
This heater stopped working after 35 days of use. Usually I get at least 1 year out of a heater. Try another brand or store.
