I recommend the Tulsi oven for anyone who is serious about saving energy. I've used it a number of times since I bought it 3 weeks ago and have not been disappointed. Probably the highlight has been fresh cherry pie. The oven cooked the crust perfectly (I used the side booster panels but not the hybrid electricity). I'm going to try a pizza and meatloaf soon. The hybrid feature is a great back-up to have, although I wish I knew at which temperature it supposedly kicks on. The clips that hold the oven shut when not in use are extremely cheap-looking and flimsy. I know it is a matter of time before they break. Tulsi could have dropped a few extra cents and installed clips that will last. Finally, the oven instructions were obviously written by a non-native English speaker and are a bit hard to understand at times.That aside, I'm thrilled to have the Tulsi solar oven. I think I'll use it more and more, especially as energy costs continue to spiral out of control.
