I had a foodsaver that lasted less than a year with no repair or parts available.
I bought a Weston and have had no problems. I use any brand bag, rival, foodsaver, ect. all work fine.
It seals chili or thick stews with no problems. Soups I just chill not freeze.
Not that I need them, but before I bought the Weston I checked availability of repair and ability to purchase parts for self repair.
Some people swear by foodsaver, some of us have had bad experiences. I was so dissatisfied with my foodsaver I used it for target practice. That way I could actually enjoy the product to the fullest capacity even if it was only one time.
