These were compatible with the Nesco dehydrator my grandpa handed down to us that he bought in the 90s. So far these have withstood several rounds of dehydrating jerky and as many washes in the dishwasher. I expect they will last for a while. They are rigid plastic.

Got these to add to my dehydrator and they work very well. Very easy to stack

I bought two sets and increase my capacity by double. They fit perfectly.

These trays worked well and were pretty much just like the trays that came included with my dehydrator. Slightly different color but that stuff drives me crazy and I barely notice it.

I bought these as extras to put in my dehydrator. Works great.

Fits perfectly on my decade old Nesco dehydrator. The color is a little darker than the originals but I am not concerned because it is not a decor item.

Added additional space to dehydrator

Nicely made, sturdy. My FD-79 will handle up to 12 trays.

maxes dehydrating easier with extra trays

I have the 13.5' diameter Nesco Professional Food Jerky Dehydrator. I purchased two of these trays for it and they fit perfectly, although there are some differences. First, they are a light grey color with grey/blue speckles. My original trays are an off white with grey/blue speckles. Secondly, they do not have the crown-shaped vertical center spokes surrounding the small hole in the center that my original trays have, although this appears not to affect the function or stacking ability. Finally, it is lighter weight and less sturdy overall. There are fewer spokes, which results in the spaces between each spoke being larger. There are very few things for which I wouldn't want to use an extra mesh screen on the tray to keep food from falling through the cracks. All in all, the trays will function, but I do wish they were the same as my original trays. My dehydrator is at least 10 years old though, so perhaps this is simply how the new ones are made. Possibly if your machine is newer they will match.

A couple of the original rings started to break apart after many years of frequent use. These are the exact same rings and are working perfectly so far.

Have an old American harvest snackmaster dehydrator that I primarily use for beef jerky. These trays fit perfectly with the existing ones and allow me to dry a larger quantity.

One tray has an incomplete mesh, as if insufficient plastic was injected into the mold. (It still probably works.)

Fits perfect works great

These trays fit just like the old ones. No issues with cleaning. Would recommend

Was able to add 6 trays for a total of 11.

Works great

These are so much studierr than the clear ones I bought the last time.

It fits but the center is different than the ones that come with the machine, and I don't like it no edge
