I have used it twice for small amounts of mint and small tomatoes. There were two cook books included with the book but they did not agree with times and heat temps and the tomato time was off also. I feel this process is going to take time to learn and investigating from different sources. I am going to enjoy this. As I have never used any other type of dehydrator except a warm onion (pilot oven) and this is much easier.I bought the middle of the line version. In my opinion this brand is overpriced and is not recommended for use in humid climates. It has a lot of room and looks good, but I fear it is not built to last... We'll see.I returned the first one because I thought the seams didn't line up correctly on the top. Second one had the same allignment, so I assume this is part of the design. Works great. Hard to see the control knobs in back when it sits on the counter in my kitchen!I received my dehydrator and have used it once it was quick clean ur was easier than the old plastic trays I had. I have no ordered the stainless steel trays since I do meats for dog treatsLove my dehydrator, I've made Kale chips and dehydrated some almond pulp after making almond milk. I am so excited about the possibilities!
