【Newly Upgraded Quality】Two super-tough heating tubes are made of explosion-proof quartz glass and high-temperature-resistant nickel-chrome heating wires, distributing heat evenly and heating water faster. The shell is made of V0-rated flame retardant plastic which is corrosion and heat-resistant and prevents fish from touching the heater, thus preventing them from getting burned.
【Multiple Security Protection】When the water temperature exceeds 94°F or the top of the submersible aquarium heater is 2 inches above the water surface, the heater will automatically cut off the power and stop heating, it will display an error code and sound an alarm until the water temperature is below 94°F or the submersible fish tank heater is completely submerged in the water.
【External Digital Controller】Adjust the temperature without putting your hand in the water. The LED controller can show the current water temperature, preset temperature, and more warning signs of High temperature/ out of the water. The running red light means the heater is heating, and the running green light means the water temperature has reached the set temperature.
【Precise Control Temperatur】Temperature adjustable range: 63-94℉, hold the “+” and “-” for 5 seconds to switch between ℉ and ℃. Accuracy: ±1°F, the adjustable aquarium heater will stop heating when the temperature reaches the setting and restart when it is lower than the setting. The memory function can automatically retain the previous setting when the adjustable fish tank heater is restarted.

Great
Using in 75gal aquarium. Working well so far. Easy to install. Heats up ok at a good rate maybe took a couple hours after installing from 67 to 74 degrees. I have it placed horizontally like instructions say you can, and prefer it. Helps to avoid water levels dropping below heater. Good price. Hope it lasts!

Impressive heater
I have many tanks so tend to keep emergency heaters, medicines and supplies on hand. Luckily when an older heater failed in my 120 gallon, I had one of these still in the box. Knowing I really needed a 500 watt for such a large tank or two 300 watt. I set it up thinking it would help until I could get a second 300 watt or a 500 watt delivered. Finished my water changes and went back in two hours to check on it. Not only did it keep the temp from dropping in a room ten degrees cooler. It had already raised tank temp 4 degrees . Impressed. So I have already ordered another back up.

This is a great heater
This is the second one of these heaters I have purchased and I really do like them. They work well on my 15 gallon tanks. I did have one that went defective after about a month but they replaced it and sent me a brand new one so it worked great too. I highly recommend this heater for a tank within the size of 15 to 25 or 30 gallons the most, and I really love the fact that it has a preset temperature and you can see the temperature.
