I have an Excalibur 9 tray dehydrator. I got it mainly because so many on forums like this were saying how good they are. I needed to get serious about my preps so I sucked it up and bought one. I must say that I've had limited success with it. Either I'm not doing it right or that's just the nature of dehydrated food. Frozen vegetables and dehydrated rice are the best so far, and collard greens out of the garden. When it comes to fruit I'm downright scared to eat it. I leave it going for days and it's still sticky. I can't ever get cauliflower, broccoli and squash, to name a few, to rehydrate correctly. I don't care how long I cook them they seem tough. What am I doing wrong?
