    Complete garbage!!!!!!!!!!
  

*by J***N on Reviewed in the United States on January 23, 2020*

I bought this heater as a back up water heater in case one of my current one breaks in the middle of the night. I needed a heater for an isolation tank for a sick fish and was working fine up until I had to clean the aquarium. I disconnected the water heater carefully removed it from the aquarium with no issue. Once I filled the tank back up and set the heater back up and reconnected I heard a loud pop from the water heater. I removed the heater and the glass had cracked after 10 days of use.

    I'm pleasantly surprised!

I was a bit skeptical at first as to whether a cheaply priced heater would work for more than a week in a decently sized aquarium. To my surprise this aquatic heater is working pretty good so far, it's been plugged in for about a week and keeping a good stable temperature of 80 degrees farenheit in my 40 gallon aquarium. It was shipped to me super fast and tracking was very accurate. Although there is little to no english on the box or instructions. It was very self explanatory and easy to set up. I would definitely recommend this product to someone who needs a quick cheap aquatic heater in a pinch or to someone who needs an aquatic heater in general.

### ⭐⭐⭐⭐⭐ 







  
  
    So far so good.

The products seems to work accordingly. It can use temp numbers on the device. So you can know what you are setting it to. You kinda have to guess at it and keep the thermometer inside for a reading. Also English instructions would be nice to have. The cover is great.
