Got an older model about 8 years ago. Soon after, it would suck the air out but not seal the bag. Fussed with it and it worked occasionally. Finally got fed up and stuck it in the cupboard. Would pull it out now and then. Sometimes it worked, sometimes not. Just called the 800 number. After troubleshooting, guess what, I need a new unit. They will give me a discount of 15% off retail. Yippee. Why would I buy another unit after having such a bad experience with this one? Food sealing is a great money saving practice. FoodSaver, on the other hand brought me nothing but problems. The greatest thing about this machine was the feeling I got just moments ago when I smashed the damn thing with a sledgehammer! Sweet relief!
