Just used this for the first time today - dehydrated oranges, apples, mushrooms, celery, carrots and tomatoes.
We were really impressed by how evenly it heated. Everything went very well. (Notes: celery evaporated to almost nothing and the orange slices are going to take more time than the rest)
It looks nice, works well, and is easy to use. My only warning is that because it uses air flow, the back wall is just one big vent, so heat is going to escape, making this less desirable to use inside on hot days, but great during the winter (and it really doesn't seem to bleed heat as much as I would have expected - I guess because it's such low heat to begin with.
Anyway - impressed so far and looking forward to trying some strawberries and apricots come summer.
4.5 stars (If it was a little cheaper, I'd probably go with 5 stars)
