Query: Not worth it!

As a previous owner of the 800 model which my husband and I wore out, we received the 825 as an anniversary present. It was defective, so we returned it to the place of purchase, and picked up a new one. Much to our surprise, we got home and FoodSaver had actually replaced it with a letter saying that it was an 845 in the 825 box. Fine, great. We got an upgraded model for nothing. WRONG. We got a piece of junk for the cost of the 825. This thing has been a problem all along. Unfortunately, we were out of the 30 day return from the store we bought it in. The motor grinds sometimes like it going to just die - of course, everytime we call customer service, it doesn't happen. The sealer doesn't always work. It will start and just stop for no reason. Then tonight, the customer service rep told me you can't put fresh meat in it. You need to freeze the meat for two hours before food saving it....doesn't that defeat the purpose????? I am so fed up with the machine, I want to just toss it!
