Needs major renovation

This little heater could be nice if it could control the temperature in any direction other than up. If you want it to be cooler you have to turn it off for a few minutes until the thermometer forgets its previous programming. Which still makes it a dummy device because imagine having a power outage for more than 10 minutes. Then your fish or reptile will not have the right warmth when the power returns. An article that needs serious improvement

Pros
  • Great for a small home
Cons
  • No instructions

Remembers last temp if power goes out

This is an amazing heater because when the power flashes or is cycled it automatically remembers the last temp setting instead of one select random number. I have another heater that I paid more for and would have had to turn it off if I was going away for the weekend because it was automatically set on high. So if the power went out my fish would basically be cooked when it came back on if I hadn't caught it. It's also quite small for the type of heater (digital display).

Pros
  • Best
Cons
  • I will add later

Suitable for small aquariums

Miraculously my two African Dwarf Frogs survived for over a year in natural winter room temperatures of 68-70º during the day and 65º at night. Then I read that they are happy at least 75º and ideally between 77 and 78º. So I bought this heater mainly because of its small size (my frog tank is very small). It was easy to install and adjust to 78º. During operation, however, the temperature display on the device itself goes from a minimum of 75 to a maximum of 81, which bothered me a bit. A…

Pros
  • Good value for money
Cons
  • Crumpled packaging

No longer working - fish and aquatic animals

I purchased this on February 20th, 2021. Last week I suddenly noticed that there was less water in my aquarium than it should have been. I checked the heater and it's off. No matter what I do, I can't get it to work again. only reads I had to buy another heater. Very disappointed with this product, was happy with it until it stopped working. I have the 2nd in another pool, let's see how he behaves. I cannot recommend this product at the moment. Well the 2nd did the same. I really don't…

Pros
  • Durable test results
Cons
  • Low repairability

Good product, great customer service!

I gave 5 stars. The original purchase I made was great. My heater was delivered on time and fitted the beta aquarium perfectly. Unfortunately the heating stopped working after about 3 months. I really liked the heater, but the return period has already expired. Having doubts, I still contacted the company for a replacement and to my surprise they were happy to send me a new heater. instantly. Delivered within a week! So far so good with the new heater. I'll post again in the future if this one…

Pros
  • Very good quality
Cons
  • No

Great little heater for my 3.5 gallon tank!

Addendum: After contacting the seller, a new heater was urgently sent, there is a 12-month guarantee on it. They didn't ask to return the defective one. I received it in 2 days and installed it in the tank. It already works much better than the fancy one. Keeps the temperature as described and my betta is very happy it isn't freezing. I sincerely appreciate how quick and responsive the seller was in responding to my issue. I think even if it wasn't for the warranty they would have solved my…

Pros
  • Super for me
Cons
  • Some defects

My new favorite heater for small aquariums!

Finding a heater that will maintain a constant temperature in small tanks has been an uphill battle! I put this heater in an 8 gallon tank that sits on my desk at work. The office heats up to 74°C during the day and 55°C at night and on weekends. To keep my rooster happy, I want the temperature in the aquarium to be between 78 and 80 degrees at all times. With my old heater I could not stabilize the temperature. I set this new heater to 79 degrees and even as the room temperature changed my…

Pros
  • Great design
Cons
  • I don't remember but there was something

Excellent technique - replaced under guarantee

suddenly stopped working after 3.5 months. Tried to reset by unplugging for min. The thermostat now thinks that on hot h20 the reading is 30°F higher than it should be, on 55 degrees h20 shows 85. I easily have a 12 month warranty but have no idea how to contact the manufacturer . UPDATE: The manufacturer contacted me. and mine replaced immediately. I changed my rating to 4 bcse, firstly it didn't work. However, the support response is impressive. In operation this device is impressive and also

Pros
  • nice thing
Cons
  • poorly thought out
