While this is a more expensive dehydrator it is worth it. I have used it none stop for 3 weeks now dehydrating herbs, veggies and making fruit leather all from my gardens. I have had no problem at all except read tip at the end. Dehydrates each level equally so no need to rotate trays. Love that it came with 2 tray liners for herbs and 2 for leather/ jersey. Only tip would be that you should set temp. At 2-3 levels higher than it recommends otherwise your foods just don't dry out.
