I'm not sure if that model has a "seal" button or not. Some of the less expensive models don't and when doing really juicy or moist foods, this will be an issue.
I like mine because as soon as I see the liquid starting to move toward the seal strip, I just hit "SEAL" and it stops sucking and seals the bag. Less mess and less clean up that way.
As stated above.....if there IS a lot of moisture that gets through and you think it's compromised the seal, just wipe the liquid off the last inch and double seal to be sure.
I've also found that the cheaper bags/rolls give me more trouble than the actual "Food Saver" bags/rolls. I stopped trying to save $ by buying the cheaper rolls and stopped having as many issues.
Bottom line....I started off with a cheaper model FS. I burnt it up. I finally just bit the bullet and bought a higher end model and have been COMPLETELY happy with it's performance. And I bag a LOT of food quite often. Sometimes 30-50 bags at one sitting. Couldn't do that with the cheaper model or it would overheat.
