5.0 out of 5 stars Great for small tank
Reviewed in the United States on March 15, 2024
I got this for my 2.5 gallon quarantine tank. It worked great, getting the temp up to a steady 77F. My fish didn’t end up surviving its illness so I only used this thermometer for about a week, but it performed well while I was using it. The temperature sticker was very easy to read and aligned with the temperature on my other sticker.

My only complaint was the suction cup. Normally aquarium heaters will have a kind of brace holding the thermometer and 2 suction cups to keep it upright. This one just had one suction cup that had great suction but did not keep the thermometer upright.

Overall I’m pleased with this thermometer and would recommend it.

I’m so glad I got this! I have a 29 gallon tank and the heater in it was not keeping up. It was getting cooler outside here and the heat in the house wasn’t on yet so it was a little cooler in the house. The fish tank which needs to be around 80 got down to 74. The heater was on constantly and was not warming the tank up at all. I bought this and it’s been great. The temperature setting on the heater is a little off, I have it set to 78 and the tank is consistently at 80-82. So make sure you keep an eye on the temperature initially to find the right setting. The fish which had gotten really lethargic when it was cold in there are doing much better. I highly recommend this!

4.0 out of 5 stars Good heater for the price
Reviewed in the United States on April 22, 2024
I bought this heater based on the reviews and price. I wanted a heater that I could regulate. It comes with a temperature sensor that you can place on the opposite side of the outside of the aquarium via a suction cup. The suction does not hold for extended periods of time. I also have needed to reach into the aquarium to adjust the temperature setting several times as spring days have warmed up the temperature.
This is a nicer heater than my last one as it does have Way to change the temperature settings. It’s just not as accurate as I had expected.

5.0 out of 5 stars Outstanding small heater
Reviewed in the United States on April 1, 2024
I am really impressed with this heater. I'm using it in a 3 gallon nano aquarium. It came with a guard so that fish can't swim right up to and touch the heating element. My favorite part is it has both a green light and a red light. Green means water is up to temperature, Red means heater is on and warming the water. I wish all heaters had this feature. You never have to wonder if your heater is working or not, just check the light. Seems well made and keeps my water at a perfect 78°. Highly recommend!

5.0 out of 5 stars Nice heater, but kinda big.
Reviewed in the United States on March 30, 2024
Firstly, I have no idea why everyone is saying suction sucks. Works perfectly fine for me. As stated before, it is very tall. Was able to reach the top of my ten gallon. Keeps heat very well and is fairly accurate

Reviewed in the United States on April 8, 2024
I’ve had been had other heaters that haven’t lasted as long as this one. Steady temperature control. I recommend putting I under or near the in flow from your filter for even heating, and deep enough so it’s not exposed during water changes. Comes with a digital display for temperature so you don’t have to strain your eyes reading those strips that stick to the glass. Price is great as well.

3.0 out of 5 stars Had a Weird Defect
Reviewed in the United States on January 9, 2024
I have purchased 4 or 5 of these Orlushy heaters and for the most part they have worked well, but one developed a strange issue rendering it unuseable. It was doing the job without issues in the tank but I was blowing circuit breakers and didn't know the cause. I had not found the problem but one day moved the heater to a different tank on a different electrical circuit and that circuit started to blow it's breaker. After a few days I noticed the problem had stopped on the first electrical circuit, no more blown breakers, but I was still blowing the second. So I moved the heater onto it's own seperate circuit and that one blew in five minutes. Meanwhile the problem ceased on the second circuit. Since stopping use of this heating unit, I have not had any blown circuit breakers. Conclusion: The Orlushy 150W Heater was the reason I was blowing my circuit breakers. Although the other units I have are still working properly, I have lost faith in Orlushy and will not be patronizing that company in the future.
