The issues vary but aren't consistent so not precisely sure why they occur. Sometimes as bag fills up, it slips off. We have to cut slits in sides to fit into the compactor knobs that hold it in place, sometimes slips off the knobs. The plastic itself is pretty good. We pack in plenty and compact a good deal, the plastic bag doesn't rip, pop or otherwise leak.Despite these small issues, they don't seem to affect the durability of the bags. For the price point each bag works out to approximately .50 cents a bag, and this can't be beat.Fitting the bag. Not very easy, our compactor is rectangular, sharp edges. Slipping the bag on is always a bit of a chore, getting it over edges but after that, it's smooth sailing. Isn't the worst thing but for some could be a turn off. There may be better quality products out there, but this is pretty good despite the small issues stated and the price point is fair, in my opinion.
