I’ve had SO many dehydrators, but my current one is better than all of them combined:

Excalibur 2900ECB 9-Tray Economy Dehydrator, Black

I really can’t go back to any other dehydrator after owning my Excalibur. The Excalibur is a spectacular device. Literally you just place your food, like kale chips or sliced bananas on the dehydrator sheets and let the dehydrator do the rest. Turn it on for 20 hours if needed and you don’t have to worry about it. High quality product. You can get it here on Amazon:
