Excallaber is a brand of food dehydrator that has been around for ages. I had been given and old one many years ago and loved it. I moved a few times and that one went to a family member, but then last year I had to buy another one. In my opinion, the quality of this brand is outstanding, and it would be the last dehydrator you'd ever have to buy. Mine is a workhorse and most people I know who use a dehydrator regularly and have an Excalibur agree this one is the best. It has "drawers" that pull out and the fan/heat comes from the back (not the bottom) to give even dehydrating. It's really the best and I highly recommend it!
