This heater does a great job. It's a must have for an aquarium. It does a great job of making sure the temp is right where it needs to be and the thermostat makes it that much easier.

Pros: It's like they have their own spa

Cons: none

I like this brand of aquarium heater. Not only does it work well and is easy to use, but it is fairly inexpensive. Also, it last a long time and is durable enough to use with large, aggressive fish.

Pros: easy to use, reasonable price

Cons: none

We have three of these in our 125 gallon reef tank, to keep the temperature just right for the fish. Marine fish are very sensitive to changes in their environment, and we can depend on this to keep the temperature in the right range.

Pros: dependable

Cons: none

This heater does its job with no fuss. Though a little expensive, the peace of mind is worth it! I used a thermometer to monitor the temperature in addition to adjusting the dial, which was a few degrees off. Still the best heater out there.

Pros: Reliable, heats how it's supposed to, does its job

Cons: Expensive, dial is not always accurate

Have had this heater for five years, and it is still very accurate and dependable.

Pros: very accurate

Cons: none
