This chip sealer is a tad finicky but ultimately it does what it needs to. It can be hard to get it started on a bag, since you need to be able to hold the edge and pull it strait. After a couple of trials we found starting in the center of the bag and pulling to one side then the other was the best option. We have heat seal bags that shrink with a heat gun. this device cuts off the excess plastic as it seals the edges for us. I'd prefer to have the edges on, but it can be a useful aspect as well. I love the color options and that it has a hook to be able to hang up out of the way between uses as well, and its the perfect size for travel if needed!
Pros: Color options, functions as it should
Cons: hard to master at first, can't seal whole bag in one sweep
