I have used the force-flex drawstring bags before and have had trouble with the top part ripping off every time I try to take the bag out of the can. I decided to try the force-flex plus bags thinking they might be better, but the problem is still there. It's like the bag is perferated right where the drawstring is at along the bottom of it. The tie bags work fine, but would prefer the drawstring type if they didn't have this major flaw in their design.
