I absolutely love these lids. It really has upped my game in freeze drying leftovers and freezing them before freeze drying.
I have received and have used these tray covers now 4 times. They stack well, protect the product in the trays and work almost perfect. The only drawback is they hold on to tightly and are a real struggle to remove when you have them in your freezer before freeze drying the trays. The cold makes them stiff and are very hard to remove from the product trays.
These lids are really helpful--before, I was using flimsy 3D printed stands, legos, and mason jar lids to separate trays. Often, the trays would touch each other and get stuck to each other.
Now, I can prep and freeze trays for a full freeze dryer load, stacking them in one corner of the freezer. It's a space saving game changer.
Just received my FD tray covers. Been waiting for a long time for them to be manufactured!!!
Thanks. A bit pricey but just what the doctor ordered. Love them!!
So excited to have these lids. I can stack my trays in the deep freezer now. They have made a big difference in space .
