Worked for four months

This was a good thermometer for about four months before I realized it stopped working. The temperature settings seemed to be a bit higher than I set them to be, but this is easily remedied by lowering the temperature. There was no broken glass in the block. It just didn't work anymore.

Pros
  • Easy install
Cons
  • No automatic

No heat at all

I bought this for a 55 gallon tank. I set it to 80° BC, which is the temperature my turtles need. The turtle tank does not heat above 68.8°C. I even set the target temperature to 94° and gradually increase it every day. When I dip my hand in a tank of water there is no change or heat coming from the heater.

Pros
  • Absolutely amazing!
Cons
  • Contact Seller

Betta 10 gallon tank heater works great

I've had this filter for 3 or 4 months now and it works great. The only thing that wasn't great is that a lot of reviews say it's not working anymore. The only thing related was that the digital thermometer stopped working, luckily I had a spare, so far everything is fine. :) so I suggest having a spare thermometer with you just in case.

Pros
  • Sleek design
Cons
  • So far so good

Thermostat failure = dead fish

Attention buyers. This heater is just over two months old and I got home today all my fish are dead and the tank is just under 100 degrees. The heater will not turn off no matter what temperature it is set to. Apparently the thermostat had failed, taking all of my longtime fish friends with it. Buy the best device from a well-known shipping company. You get what you pay for.

Pros
  • Hands-free operation
Cons
  • Reliability

Lasted 43 days before failure

Lasted 43 days before failure. I don't think I will trust these heaters again. Thank goodness I'm keeping a close eye on my pelvis, the temperature started to rise without warning. In the morning everything was fine, after 9 hours the temperature rose by 10 degrees for no reason. The light was on like the water wasn't hot enough. I had to get it out of the water.

Pros
  • Very Impressive
Cons
  • Quality

Do not buy this product.

Everything worked fine initially, I have a 65 gallon salt water tank. The heating element stopped working twice. There is no heat light. After turning the thermostat knob, it starts to warm up, but then stops. This product is less than a year old. The bonus digital thermometer sucks, it reads 8 degrees below actual temperature. Verified by 2 other devices.

Pros
  • Sturdy construction
Cons
  • Volume

Save money on aquarium heating and cooling equipment

I have African cichlids. I set it to 78° and checked the next day. It was 85°-86° so I now set it to the lowest setting of 70° and it stays at 79.5°-80°. I wouldn't have to do that if it works properly. It's terrible to ask me to send me a new model of this model. I read stories about whores in these reviews. I will not expose my fish to this. But it took me a week to get it up to that temperature. Not what to do. I could kill my fish trying to regulate the water temperature. When I bought it I

Pros
