I had a different brand of food saver before and it quit working. I bought this to replace my other one. I had a bit of a hard time getting it to work right off the bat, if you dont put enough pressure on the middle of the machine it doenst create the right amount of suction. I dont mind having to hold a bit of pressure on the middle but its not quite as hands free as I would like. With that being said, once I figured out how to create a better suction the machine was very fast, took about 5 seconds to pull all the air out and seal the bag. So far I am impressed.
