That's what I used to do:
I have a real old one & another pretty old one. Both of them need a rest after doing both ends of about a dozen bags real fast, so I used to swap them to let one cool while using the other one.
Then I got a huge order of bags from Lisa.
Now since only one end needs sealing, I don't have to let my newer one cool off.
So I got about 500 of each of the two smallest bags, and a dozen rolls just for bigger oddball items.
That solved my overheating problem.
And I think the bags end up costing about 30 cents each.
What was really nice when you finish baggin, there is a little button on the side to push and it cleans up the grinder and stuffer too. I had not downloaded that app yet though, so I'll have to wait to see how well it works.
I can feel the diffrence in weight between Lisa's bag and those that came with the unit. I am thinking they will easily stand up to fresh, headed shrimp if I will dial the pressure down to the lowest setting.
Well thank God for Sam's, been buying cases and cases of "Freezer Ziplocs" for many many many years. I was really wanting a slicer, but what put the stray that broke the camel's back, I had another entire case of quart ziplocs that leaked AND it was at a very bad time. THEN I remembered the last case did the same. Sure they'll send you your money back. a mear pitance to the amount of frustration it causes. And they can break and leak into the freezer too.
So this was the right buy at the right time and it really has to do almost nothing to beat its competition! I will say I could buy a load of bags and throw away to justify a sealer as good as what this one looks.
Cheese just isn't a good topic around here right now....LOL
