We purchased ours a month ago. So far we have only done beef jerky and venison jerky. Overall we love it.
It's large. This is not an item you can leave out on your counter unless you have a very spacious kitchen. It is large! Ours has a home on the basement shelf and I send a boy to fetch it when I need it.
It has plastic trays. They sell stainless steel ones that you could purchase separate
It is expensive!
Trays still need to be rotated for even dehydrating
Rectangular trays. Much easier to load up with jerky than those silly circular trays. We fit about 15 pounds of wet meat in one batch.
Quiet. It does have a constant hum but can be lessened by making sure no trays are touching the interior back panel
Produces a consistent product. Batch after batch has been the same allowing us to tweak other areas of our recipe without worrying about a dehydrator that works differently each time.
Long lasting (not from personal experience but did lots of research and many folks out there with 30 year old excaliburs)
