First time dry aging

What I have found is the more sophisticated the model of FS the more difficult it is to seal a UMAi Dry bag! My favorite one I use is an old style “stupid” 2200 model which doesn’t try to think for me! The best advice I can give you is to turn off any automatic assistance that you can turn off or override and then using even an old used UMAi Dry bag practice sealing it several times until you get the hang of it!
