Got mine today. What a poor buy! For the money I spent I am disappointed. Started out working fine then wouldn't seal right. You can tell right away when it grabs the bag and starts to suck whether its going to suck it down all the way or not and 3 out of 4 times it would not. After wasting a lot of bags i figured out you need to hot cancel right away so it doesn't seal it when it hasn't vacuumed it yet. It took me a good hour to seal 13 small bags. The instructions say to wait 20 seconds between seals to let it cool. I did that and nothing. Then wait 20 minutes. Sealed the first one then after a 20 second wait for the second one, didn't seal right, and the error light doesn't flash as if it recognizes it isn't sealed.
I'll call it a night right now and try again tomorrow.
