Our old dehydrator, given to us by a well-meaning neighbor, was a bear to haul around. Toward the end of its life it got noisy and sort of stank as well. Well, naturally this dehydrator is like going from the Flintstones to the Jetsons. It's super-light, draws less power, throws off less heat, and your stuff gets dried. Happiness and jubilations! So far we've only done fruit, but I've had a co-worker's Nesco home-made jerky and it was terrific. I look forward to a lot of drying and such.
The Nesco 500 Dehydrator works fine. It is slightly noisy. However, my biggest complaint is that there is no "on/off" switch on the dehydrator. You have to plug and unplug for power. To me this is a safety hazard. I went back and reviewed the description and saw nothing about the switch. Some of the dehydrators mentioned switches. Many did not. I made the erroneous assumption that any appliance would have a switch. I would not have purchased this particular unit had I been aware of the absence of a switch.
