My wife and I life in Michigan and love to be out in our backyard as much as weather allows. Before patio heaters, that was only half the year. Now with this heater, and another, we enjoy Spring and Fall days and evenings and host all of our friends who want to get out, too. Fantastic!! Don't expect the heater to suddenly make your whole yard or patio feel like summer - that's unrealistic. But it definitely takes the chill out of its area, and that's perfect for us!!
Have had this unit for two months now and it definitely meets my expectation--- convenient, easy to use and makes sitting out on the patio much more tolerable during cool weather. Perfect for taking the chill out while BBQ'ing.
