AqueonAquarium Fish Tank Preset Heater For Up To 40 Gallons, 100 Watts

I love that this keeps the temperature and I don’t have to worry about it ever changing. There is a red light that comes on when it’s heating and the light goes off when it’s not. It’s small and effective!

I was shocked about how good this item is.When it first came, I thought it would overheat my tank, but I had to give it a try.So when I placed the heater in, the suction was pretty secure! I was surprised by this, because lots ofheaters' suction power does not stick well.It gets better and better! I turned on the heater and I saw the red light. I waited for a few more minutes and the light went down. At first, I thought I didn't plug the cable well, but after a while, I realized it was actually controlling the temperature in the tank. Amazing!It turned on and off, on and off. Then I checked the temperature in the tank. It was perfect!Overall, this heater is a solid 5 star!

Es la primera vez que compro un calentador con la temperatura ya seleccionada y quede muy satisfecho cumple con lo se ofrece, lo uso en un nano de 40 litros y funcionando perfecto... llega a la temperatura y se apaga.

This is a good heater, but have had a couple issues. This is my second one. The first one worked great, but after a few months, it stopped working. I ordered a new one, and this one keeps shutting off even though the water isn't that warm. Maybe it's on purpose, because it shuts off around 80 degrees, but I swear the first one heated warmer. My ideal would be about 82 degrees.

me parebe bueno para el precio, cumple bien su funcion.
