Is this heater safe for a turtle? Or will it burn the turtle if it touches it?
Answer by ChewyJan 22, 2018
Although this heater is specifically designed for fresh and saltwater fish, pet parents have reported it being safe for their turtle's tank.

I realize how stupid this question is, as I'm sure it probably does. But, I like to be thorough. So, does this unit come with suction cups to hold it in place? And if so, can I mount this horizontally near the bottom of a tank, but above the gravel, without damaging it?
Answer by ChewyJan 25, 2018
Suction cups are included with this heater. The 50-watt and 100-watt include one, while the 100-watt and 200-watt bring two suction cups.

The light turns off after 1 min does that mean it's defective or is it supposed to do that
Answer by ChewyDec 19, 2018
This heater features an automatic safety shut off and overheat protection. Once plugged in, the heater will automatically start working. Should your water need heating, the indicator lamp will illuminate showing that the heater is functioning and in heating mode.

Is it normal for the red light to kick off and on?
Answer by ChewyMar 21, 2020
Should your water need heating, the indicator lamp, will illuminate showing that the heater is functioning and in heating mode.

50W review - great for 10 gallons and less

If adjustable I would have given higher marks, but in our 10 gallon and 5.5 gallon it works great! You need to consider ambient room temp when picking power for your heater, not only the watt size. This one was able to take 60 degree Fahrenheit room temp and convert to 74-78 easily. Have only had this heater for 6 weeks, so can’t comment on longevity yet. For larger tanks, buying multiple heaters instead of one big one protects against one big catastrophic failure.

Does not maintain temperature

I have had the heater for 3 months now and I noticed this morning that the water in my tank was in the 60s. I tried unplugging the heater and letting it sit for 10 minutes before plugging it back in. The heater would not turn on.

very deceiving description -

I have TWO of these heaters in my tank and they don't heat the water at all. My turtle clings to the heaters to try to obtain some heat. I would never buy them again.

Bad product

I got this for my 20 gallon tank with mollies and betta fish. Turns off constantly, and doesn’t keep the water at the right temperature. would not recommend.

Doesn’t hold correct temperature

This preset heater is supposed to keep the temperature at 78 degrees but despite being the correct size and in a room that is 74 degrees, it will not keep the water above 75-76. I’ve tried moving it as close as I can to the filter to evenly distribute the warmed water, but it’s just not working.

Bad Heater

This heater has only been in a 30 gallon tank 10 days and it broke. Lucky we didn't lose any fish.
