Review on Hygger Titanium Aquarium Heater: Digital Submersible Heater for Saltwater & Freshwater Tanks - Ideal for Fish Tanks Ranging from 5 to 120 Gal by Andrew Hare

I have purchased 5 of these heaters, 4 have been in use for some time and 1 is waiting for another aquarium to be installed next weekend. Everything works great, accurate and very easy to set up. If there were one improvement element it would be suction cups, but that basically goes for almost any product that uses suction cups to attach to the side of your tank. The fact that large African cichlids and loricariids occasionally come into contact with the heater may also be a factor. The fact that I recently bought my fifth Hygger aquarium heater in two different sizes is intended as a recommendation and a sign of how satisfied I am with the product.
