🐠 SZELAM Aquarium Heater: Upgraded 100/300W Fish Tank Heater with External Controller and Split Temperature Probe - Auto Shut Off, Ideal for Betta Fish and Turtle Tanks Review

Better than any other heater on the market for the price. The water temperature reading is about 1F higher than the actual one. That's actually very good. I would definitely buy again.

Broke after 4 months Didn't realize it until it was too late, was killing my fish and coral Something as simple as a heater should undoubtedly last much longer The reliability and the quality of this product is terrible. All I have is a code that says E0

I bought this to heat a 40 gallon accumulator. He says it will heat up well over 40 gallons to 93 degrees. I plugged it in and after 3 days my tank went from 44 to 67. That's as much as it gets hot. It sucks because I need 90 degrees. Very disappointed and misled.

My sliders damage everything in sight. They pulled this baby out overnight, he was stepping over the water and the whole bedroom smelled like burnt plastic. Half of this thing was without water. It will work for fish too. That's why I gave 5 stars! It works on fish and will definitely warm up the tank quickly. Only if you have turtles that destroy everything, don't take these. Get a smart one that turns off automatically. I did and it works great

I will not buy this heater again And if you are reading this post do not buy it because I finally put it in my tank. Bought them a few weeks ago Chance to put it in there I finally got it in there yesterday, set the temp to 78 and I woke up this morning and it's killed all my saltwater fish. My corals are my enemies because it has risen to 93 degrees. I am so angry and frustrated that this product is rubbish here hundreds of dollars down the drain what i get i should have bought a more…

I purchased this item a few months ago and it worked great initially. I was able to set the temperature and then monitor the temperature with a digital thermometer which was amazing. Until I came home to a dead aquarium. My tank cichlids are set to 80 so I know how glass usually feels, but when I touched the glass it was very warm. The thermometer on the unit read a water temperature of 60 degrees Fahrenheit, causing it to attempt to hit the 80 degree Fahrenheit mark while continuing to heat…

I was always frustrated with aquarium immersion heaters because they were very difficult to set up accurately. This heater makes it easy to set the exact temperature you want and also displays the actual water temperature, eliminating the need for a separate thermometer. The controller mounts outside of the tank, so you don't have to reach into the water to adjust the heater. The numbers on the display are large and easy to read from a distance. It also includes an automatic shut off in case…

I don't like writing bad reviews but I'm always honest. I found that my turtle wasn't eating, probably because the water was too cold. I bought this heater and it worked great, the water heated up, the turtle started eating, life was great. About three weeks later the error light came on and I couldn't fix this error so the water got colder. I ordered another brand and it has worked so far. I bought this item so I can regulate the temperature. from a connected remote control outside the tank…

I have 3 red earworms in my 29 gallon aquarium. I use a ZooMed TC-32 filter and a 6" aeration stone to purify the water. I'm very happy with how it looks and even more so with its capabilities. This heater is near the inlet of my filter, and I have a separate thermometer on the other side of my tank. The temperature on the reader (through a probe attached to the heater) is only 1-2 degrees different compared to the thermometer. The only minor complaint is that the suction cups don't stick like…
