We have tried a few, and if it’s for soups and things, it doesnt hold the vaccum for very long. What we have found works better, is adding blood absorbing pads to the bag first and put the meat on top.
The pad absorbs the extra moisture, so it doesn’t end up in the vaccum sealer.
I get mine here
Lem absorbing pads for vaccum season
I went through several machines before I found out, I just needed to add these. Hope it helps
