Great controller for my aquarium

Cons
  • Overall, I highly recommend this product to anyone looking for high-quality aquarium heaters and chillers in the Pet Supplies category.

Poor quality product

After I bought an 800w woliver aquarium heater for my fish pond it stopped heating after only 10 days of use. There were no error codes, the heater just stopped working. I will not recommend this product to anyone!

Pros
  • aquarium heater and cooler
Cons
  • poorly designed

Wow, this one is sturdy

This aquarium heater is so powerful and large that it heats up the entire aquarium quickly and efficiently and there are very few parts. It's very easy to set up and easy to use, you just press a button until you reach your desired temperature and you're done. I highly recommend this heater.

Pros
  • Fish and aquatic pets
Cons
  • The cord is shorter than the others
