I bought this product for my 700 liters tank. I adjusted and set up the heater at 30 degree Celsius and it maintain the water temperature between 24.5 and 26 degree between day and night. I have been using it for a month now and I have no problem so far. I am happy with the product.

Very easy to install & I love that it automatically turns on & off according to the tank waters temperature, as our weather is so erratic.

Good looking heater, with protective plastic case. Heats water as it should.

Great item great price. Suits my outdoor pond. Bonus with the guard that comes with the heater
Great product ,works perfectly, easy set controls
Temp control gauge is not totally accurate, but once you find the right setting for your needs, it works well.
Not used yet, but well packaged and good price.
product is safe within the tank as well as fitted to the rear. cleaner shrimp seems interested but cannot hurt itself so that's definitely a bonus
Was a lot longer than I expected.....the measurements may have been listed but I missed them. Havent got it in aquarium yet so unable to comment on performance.
The heater seems to work well, however I had to stop using it after a few days as fish managed to get inside the plastic cage, I lost 3 decent sized tetras and found them in there, the gaps on the front are small but there are larger gaps at the back which is accessible to the fish
