I am using this in an off-label application: It is heating a 110 gallon deck pond on my back porch (full outdoor exposure). There is a very large pleco in there so I have to be able to maintain a near tropical temperature through winter. Worked just fine outside during this past winter '14/'15 here in New Jersey. I did have this 800 watt plus the 500 watt in there and the tub is fully insulated and covered (in winter). The control box is not for outdoors so I did build it a plastic shelter to keep snow and rain off.
I did water changes throughout the winter which would drop the water temp down. The heaters would kick on and get the temperature back up very quickly. If there was a greater than 10 degree drop, the heater does cycle on and off until it reaches the set temp.
The heater works nicely. The controls are easy to read and to set. The alarm feature works fine. I especially like the digital temperature display. Very easy to read on my way out the door everyday. I do keep a 2nd thermometer in the water just to check up and make sure it is accurate.
The only shortfall are the cords which like other reviewers stated are very short! The unit has to be situated right next to the pond. I imagine with a very deep tank the cord might not reach the bottom. This extremely limits where you can hide the controller and where you can hide the heat tube in the tank.
Outside of the cord lengths, its a great heater though and kept my pleco happy all winter outside!

Ignore debbie, she wanted to be in the picture.
Oh man. This thing is a beast. Bought it for my 150 gallon turtle tank. After the initial set up (btw it WILL yell at you if the temp is too low) after my last crappy petsmart heater broke, it has kept my tank at 80 degrees steady. I didnt realize aquarium heaters needed a guard, but thankfully it came with one of those too!
