HiTauing Aquarium Heater, 300W Fish Tank Heater with LED Digital Display & 5 Safety Protection, Submersible Aquarium Heater with 2 Suction Cup and 8.2Ft Cord for 40-75 Gallon Fish Tank.

Works great ! Keeps the temp stable and can see what temp it is at all times. Highly recommend for fish tanks .

I replaced my dead heater with this model and after over a year it is still working well. It holds accurate temperature in my 55 gallon set up. I would recommend this heater to anyone who needs to replace theirs.

I really like this aquarium heater. You can set it and forget it. It keeps my 125 gallon aquarium nice and toasty. The Oscar’s haven’t been able to tear it up like the glass ones. It will stay pretty much where I put it. I will definitely recommend these for anyone with Oscar’s. They do like to tear up the tank.

This replaced a heater that was on its way out but had lasted for years. I like the temperature read outs and it seems accurate. I also like that the heater is encased in a plastic shield vs my last one. The only negative so far is that the plastic pieces look and feel cheap. I have a small concern about how long the temperature control button will last because of this. Otherwise, it seems like a good product.

The HiTauing Aquarium Heater, 500W Fish Tank Heater with LED Digital Display, is an outstanding product that has greatly improved the environment in my aquarium. This heater is incredibly efficient, quickly bringing the water to the desired temperature and maintaining it consistently.One of the standout features is the LED digital display, which makes it easy to monitor and adjust the temperature.

The intelligent water sensor and over-temperature protection provide peace of mind, ensuring the safety of my aquatic friends.The heater is made from durable, explosion-proof quartz glass, which adds to its reliability. The external digital display controller is user-friendly and allows for easy temperature monitoring and adjustments. The strong suction cups make installation a breeze, and the heater stays securely in place.Overall, the HiTauing Aquarium Heater is a fantastic investment for any aquarium enthusiast. It offers excellent performance, durability, and ease of use, making it a top choice for maintaining a healthy and stable environment for your fish. Highly recommended!

We replaced the heater that was in our tank because it just didn’t seem to be warming the tank well enough. I came across this heater which seemed reasonably priced, and read through reviews and felt confident in my purchase. When it came in, my husband “installed” it in the fish tank and mounted the temperature control unit on the wall. The design of it is nice, very user friendly. It’s now been controlling the heat for a week and has kept the tank steadily at 76 degrees fahrenheit. It is a reasonable size for our fish tank which is about 30 maybe 40 gallons (it was given to us so I’m unsure of capacity).

So far this is working well. My old heater stopped working. Luckily, I had an old glass tube back-up to get me through.The set up was very easy. I just allowed the unit to warm up some while I unplugged the old one and allowed it to cool.The unit is black and completely blends in with my back wall. I put the heater near the filter intake to disburse the heat faster.You just plug it in and it calibrated in seconds. The preset temp is 82, which is too warm. I set it at 74 with a button on the side. Within two minutes the correct current tank temp of 72 was displayed. Four hours later I am at the 74 programmed.I used a mercury thermometer to verify all temps. I read that it is a good idea to be proactive and replace your heater every two years to prevent a tragedy. This is cheap enough to do that. I will buy a smaller model for my 29 gallon tank to have ready. I put the 200 watt on my 75 freshwater.

The HiTauing Aquarium Heater works fairly well, keeping the water temperature stable in my 10-20 gallon tank. The LED digital display is a nice touch for easy monitoring, and the 5 safety protections give peace of mind. However, I’ve noticed that it can take a bit longer than expected to heat the tank, and the suction cups don't always hold as securely as I'd like. The 5.9ft cord is a good length for flexibility. Overall, it's decent for the price but could use some improvements in suction strength and heating speed.
