Firstly, it's about as loud as a lawnmower. However, I expected this as my parents have a similar model. Their model requires the bag to be fed into a slot that you can't see and it doesn't work as well. With this you only have to use as much bag as you need. About 1/20 times the bag looks really sealed, then I put it in my freezer and find out that it's not quite sealed... Oh well it still works fine. If you're doing a huge batch you do have to wait for it to cool down, but that's standard with all models. I cant really think of anything more I could reasonably ask from this thing.
