    • Perfect
Pattern Name: 300W
Like the design. Easy to use. Function perfectly, and its durability is good. A little hard to adjust heater temp.

    • Pretty good
Pattern Name: 50W
Love the heater. I am using this heater for my 10gal tank. The adjustable temperature knob is easy to access and set. I keep my temperature at about 80F and the tank's temperature stays at that value. I temperature strip is included in the product and it works pretty well.

    • Works great
Pattern Name: 50W
Works great in our 10 gallon. The dial knob at the top to adjust temperature can be a little tricky though. There is a 4 degree label gap between temps so you have to guess. Ex) 78-(gap)-82. So if you want 80 degrees, you adjust the dial in the middle of these two numbers. Not a big deal, but with me being new at fish keeping, I worried it wasn’t at perfect temperature. Other than that, it’s a good product! ... show more

Great product. Heated very fast however the reason I am not giving this 5 stars is because the knob to change the temperature was a bit difficult to turn.

PLEASE DO NOT BUY THIS! I just had a devastating loss in my tank because this thing decided it wanted to get hot and melt all all the plastic clips. It probably shocked my entire tank! I just did a water change on my 10 gallon tank. I always shut down my heater, filter, and air bubblers. Once the water gets high enough to cover the heater, I start everything up again. Jesus, I had just put the last gallon of water in the tank and all I could see was smoke. I thought it was my light, but it was coming out of the water because everything was melting. I switched the main power button on my surge protector. My fish started flopping and sinking to the bottom. I had a net that I was able to catch a few tetra fish that were at the top. My shrimp darted to the top of the tank, then nose dived to the bottom and turned upside down. I am so upset right now. I just lost 5 fish and a dozen shrimps. Probably will lose my assassin snails and two other tetra fish that I was able to get out of my tank. I have several pest snails that are now laying on their sides that will probably die. But those are not such a big deal. I spent nearly 6 months on this tank getting everything right. I just didn't have a heater, and opted for this one because of all the "Wonderful Reviews". Don't do it people. I am adding photos, not of my fish that were loss. ... show more

This aquarium heater is keeping my tank at a steady temperature, and it was easy to set up. So far, it’s working perfectly, and my fish seem happy. I’m hoping it lasts a long time, but for now, I’m very satisfied with the performance.
