Didn’t last a year

Gus is my pet snail. He lives in a 20 gallon fish tank with some plants. I bought this water heater thinking I was splurging for my snail, he’s kinda Spoiled. At first it was easy to set up and operated fine until yesterday morning when the E1 blinking light came on and hasn’t shut off since. This is a hard to set up heater vertically for this 20 gallon tank, so you must be vigilant on the water level checks so the top of the heater is not exposed. But more importantly don’t look to this heater for longevity. I luckily had a back up glass heater that’s lasted me for years without fail. Wish this was better made. Wouldn’t buy again.

I ordered two of these as replacements for my current heaters. The first one keeps flashing “El” which supposedly means it is not fully submerged, but it was all the way under the water. I put the other one and the same place and it seems to be working for now. I’m not confident in its longevity though.

No need for separate thermometer

Love that this is an all in one unit, heater, thermostat, thermometer all in one. Hate a tank cluttered with equipment which ruins the illusion of nature. The heater

Love that this is an all in one unit, heater, thermostat, thermometer all in one. Hate a tank cluttered with equipment which ruins the illusion of nature. The heater seems to be keeping a steady temperature which I have set higher right now to speed up tank cycle. Temperature display is large & bright as is the on/off indicator. For now, I’d say it works great & takes minimal room in tank. Seems like a quality product.

Compre este calentador para mi acuario y estoy muy satisfecha. Es facil de instalar y ajustar y en pocos minutos comenzo a calentar el agua a la temperatura que configure. El indicador es claro y preciso y lo mejor es que mantiene la temperatura constante sin variaciones bruscas lo cual es perfecto para el bienestar de mis peces. Ademas es silencioso y compacto asi que no ocupa mucho espacio dentro del tanque.

The temperature is very accurate.

I think they're both very reliable. I've never had these before but I really enjoy them. I will buy them again.

Sounded like a good idea

Lasted about a month, until the led lights quit working. It still heats, but I have no idea what the temp in the tank is set at
