I know own 4 Fire Sense heaters. I have three of the Pro heaters. One is located at our beach house and has held up for 5 years with no issues. I love the quick lighting of the unit, no pilot light, just the igniter. This is a great product. I have also purchased one for our kids patio and they love theirs too...........It puts out a lot of controllable heat, in a nice wide area. The SS is easy to keep clean, perfect heater
