We bought this outdoor heater one year ago after having tried 3 other heaters all of which lasted no more than 6 months each. This heater is commercial grade so very durable, will not fall over even in high winds and has no rust despite being rained on! We are able to stay very warm even in the winter (our temperature does not fall below 35 degrees in winter). We are very happy with this heater and have had no problems whatsoever.
