Bests & Worsts Reviews from Amazon

There's enough people saying they can't get it to work (and almost put me off of buying this), that I figured I'd mention why I think they couldn't: See, despite how simple a product this is, it does have a small instruction manual. And in it, it mentions to wait 3 seconds before you start sliding it across the bag, to give it time to heat up. In addition, there's a note that you have to slide slower on thicker bags, to give it time to work. I was able to totally seal a bag of Tostitos chips on my second try, once I got the timing right. I'm only giving it 4 stars instead of 5 because I only got it last night and haven't had a chance to see how resealing a bag multiple times goes, nor how long the resealer lasts, nor how much better it is in keeping chips from going stale.
