DO NOT BUY. Best in Fish and Aquatic Animals Category

The heater is fully submerged alternating between error codes hh and ll and not heating the water. The device failed after less than a month of use. UPDATE: Bought a second heater and that one failed too.

Pros
  • Great for me
Cons
  • Empty

Great digital heater

I really like this heater. The temperature controller hangs on the outside of the tank for easy adjustment. Easy to read with large number. The only thing I would change is the length of the cord from the temperature controller to the outlet. But in general everything is fine!

Pros
  • Easy to install
Cons
  • No paint required

Thermostat failed after 100 days of use

Looks like this unit went out of warranty last night. Window. The thermostat kept giving a false high of about 8 degrees, but I checked this with a secondary. Today the alarm continues to go off and reports more than 30 degrees Celsius. The actual temperature of the tank is 74 as it has stopped heating. Not a good buy. 😕

Pros
  • Handsfree
Cons
  • Security

If you want something that beeps randomly, get this

This thing beeps more than an angry NYC driver. We've tried taking it out, unplugging it, leaving it unplugged for a few days, restarting, pressing buttons, etc. It keeps beeping randomly with a high temperature warning when the water is still VERY cold. Luckily we have an adult red-eared slider. So the temperature of the water doesn't really matter - it'll just move less when it goes into their version of hibernation. As far as I can tell, it didn't work at all. Despite the message about…

Pros
  • Sleek design
Cons
  • Not as good as it says it is

I had a hard time keeping the right temperature, too big for my tank

The temperature was rising, so I decided to try this 100W. First, it was too long to fit in my aquarium. The top stuck out about an inch and touched the bottom of the tank. I liked how it has external temperature control and a reading area. It has an "actual water temperature" and a "set temperature" so you can see where your tank is. I felt like I had to set the temp a few degrees higher than I needed to get it to the desired temperature. I have a small filter and an air stone that circulates…

Pros
  • . Fingers crossed.
Cons
  • . Lots of stuff.
