I'll also note that the rolls and bags go fast! I got a 10-ft roll with the unit and was able to vacuum seal just under 8-lbs of bacon and ran out. I ordered 2 large rolls, 2 small rolls and 20 of the gallon, quart, and pint bags so we would try all of them and see what we like before stocking up on a lot of one thing. I ordered the stuff on Mon morning and they arrived from Cali on Thurs.
I like the ease of use of the bags since they are already cut and sealed at one end. The problem is you have to store them somewhere handy. The rolls are more versatile since you cut them to whatever size you want but then you have to seal one end, fill it, then seal the other end. To me this seems like it will make it die faster doing 2x the sealing, maybe I'm over thinking it. Storage is easy because the roll fits inside the machine. The extras just keep in a box out of the way. As I write this, maybe the bags could be rolled up and stored in the machine.
