Nesco American Harvest MS-2 Clean-A-Screens for Nesco Food D

Purchased 3 sets of 2 screens for our Nesco Gardenmaster Food Dehydrator for small items that fall through the drying trays. The one included with the machine is good but the extra ones just purchased r poorly cut out and r warping badly. The food just rolls off the outside edge all around and off the warped areas. Not impressed. I needed them badly and had to wait for a week to receive them and this is what I received.
