I started to use my Foodsaver with the rollers provided in the camera. No they are not good (cut to size, it is), but they were, in the words of Internet users, and contrary to the idea that one can make, the less economical than bags. And I checked! Just that you have poorly cut the bag (a bit too short for example), hurt welding, it only remains for you at the end of the roll a piece of ridiculous bag ... And all this is wasteful ! Now back at the price that hurts the heart!
So I ordered the bags and it's perfect: several possible dimensions, impeccable welds, recutting always possible if too large. I prefer!
