I had this heater for less than a week. I had trouble with it immediately - it was turning off long before the water reached the right temperature, so it wasn't heating my tank. They also only included one suction cup instead of two, so the heater wasn't very secure. I had to grab an extra suction cup that I already had. I set it a little bit higher than my target temperature and that seemed to work. I left the house for a couple days and came back to find that my water was over 95F (it was set to 81F) and half of my fish had died.The thermometer itself is okay, though it disagrees with my other thermometer at times by as much as 5 degrees (as to which one is correct, who knows.) The heater, though, has left me deeply disappointed and with a crashed tank full of dead fish. Clearly the thermostat was defective in the one I received.

It’s taking some time to get the temp just right. 85 made it almost 90° so I turned it to 70 and then the water became freezing at 68°. So now it’s on 80 and just starting to get to the right temp. The thermometer works great and I like that I can turn it off and on and that it’s not attached to the heater.

El termómetro marca lo que quiere termine usando uno de mercurio, y el calentador no mantiene la temperatura sube o baja según se le antoja, malo de verdad aunque se veía de mejor calidad

For the first month this heater worked great. I was so excited and impressed. The temperature was off by a few but other than that I really liked this product. A few days ago it stopped working. It would turn on for a few minutes then stop. I’m not really sure how to fix it

Just updating nearly a year later and no issues! Excellent heater. I was replacing my heaters fairly often, failing every 3-6 months and it was becoming costly. After writing a post asking everyone for advice on best heaters, this company contacted me and asked if I’d put theirs to the test. Well tried..tested… and true! They have been great!

Before committing this To my larger 75gal tank i tested this first in my 20gal tank. Within 10 minutes of setup & plugging it in the water was at a nice temp of 79 deg. which is where my mollies like it. Its relatively compact in size (approx. 10in from top of the bright orange dial knob to the bottom of the heater.) compared to similar models in the price range.You can either set it on the side or bottom of the tank glass. I like having it on the bottom for better view of my fish. Unfortunately this can make it difficult if I need to adjust the temp.The included suction cups help keep the heater securely suctioned to the glass where its placed. You really need to use the suctuon cups otherwise this lightweight device will float to the top. The entire heater, including the orange dial must be submerged fully in the tanks water at all times to make sure the device is working properly & distributes heated water evenly.It also came with a tank thermostat that is connected separately from the heater. I keep the tip of the thermostat at the farthest end of the tank away from the heater for the most reliable reading. Easy to adjust temp to desired reading by tapping the button to the desired temp.reading the temperature on the easily viewable screen.There are so many Pros to having this heater and only one Con - difficult number reading. Other than that this is a nice looking addition to any tank & can easily heat tanks up to 100 gal.
