Those circular stacking dehydrators work well for herbs and other thin and relatively dry products, but once you get to drying juicy stuff like figs, apricots, plums, etc, they're not as good.

You have to constantly rotate the trays and the goods dry unevenly... :( We had a similar machine, but gave it away, it was frustrating and needed constant attention, like every 1-2 hours or so.

After much deliberation, we chose an Excalibur dehydrator, which has two fans in the back and drys 9 trays evenly. Just set and forget. Saves tons of work and fiddling and can dry three times the amount of out previous machine!
