Stopped heating after 1 month
Bought 2 of these back in January. Didn’t even heat after one month. Waste of money and couldn’t return, as return window was up. Extremely dissatisfied and disappointed

Bought 2 packs, 3 out of the 4 worked
I’ll start off by saying the heaters are too long to put them vertically in a 10 gallon tank.I had to place them horizontally in my shrimp tanks because they were sticking out or digging into the substrate in every individual tank. Regardless they have been doing the job and keeping my tanks at exactly the levels I need them to be to breed. I just had trouble with a single heater that wasn’t working or adjusting the water levels no matter how high or low I would change the temperatures.If you’re budgeting and need heaters in bulk this is the way to go. If not I would say just go to your local pet shop and but a single heater at the watts you need for a tank. Constant fluctuations in temperature are never good for your tanks!
