Good heater
The heater works great and keeps the tank water to the desired temperature

Great heater
I got the 50W for my 7.5 gallon tank. I’ve never had a problem with this heater. It’s always heated my water to my desired temperature. The only thing I would suggest is to monitor your water temperature within the first couple hours of introducing the heater as it needs some time to adjust.

Keeps things warm
Works as expected. I use it for my chickens. I have their water in a 5 gallon bucket with those little orange nipple valves installed on all sides. I have this thing cranked up to 90 degrees and amazingly it keeps the water and the valves from freezing even when the temp dropped down to -9 degrees F. outside. So the chickens can get to their water on days when a water bowl freezes solid inside of a couple hours.

Heater thermometer is inaccurate
I brought the 100 watt version The heater works fine, however the internal thermometer is inaccurate. I have a separate Thermometer in my aquarium. When I set the heater to 78 F. The separate thermometer was reading 70 F. However the room was very cold. So I assumed it was struggling maintaining temperature. So I added a small 50 watt heater from tetra which was set to 78 automatically. The temperature went from 70 F To 74F. I decided to raise the temperature on the hiptop heater and now it holding to 77F. Which is fine for my needs.

Cheaper and WAY better than aqueon

Great steady temperature
Easy to get temp regulated and holds steady, submersible horizontally or verticle and none guard on end.

Good heater
For smaller tanks this has been an amazingly reliable heater, doesn't look bad has been durable, very easy to use as a plug and play and does not take up a ton of room in my 10 gallon tank

Works, but barely.
Technically it works but certainly not well. I’ve had to turn this heater more than 6 degrees (f) higher than listed. Water temp does not stay stable. I’ve been using two different thermometers to measure temp fluctuations. Will probably have to buy a different heater before I add a betta to my tank. Can’t recommend this one.

Will be happy if it lasts at least 5 years
