I purchased an Electric Parasol Heater (Model No. 60404) for my patio umbrella. It was easy to install, attractive, and performs like a champ. It is also attractive without drawing attention to itself. I also like the feature that allows for three different heat settings. I have owned 3 of these. The first was destroyed in a windstorm that also destroyed the umbrella. The insurance adjuster had never heard of the item, and after he saw it, he called me later to tell me he had bought one and how much he and his wife were enjoying it. The second fell victim to the ravages of time and use. The third is this one, and I will keep buying them. They put out just the right amount of heat.
