Bests & Worsts Reviews from Amazon

I debated buying these at all due to some of the extremely negative reviews. And and maybe those people actually got a bad set. But honestly at this point I really think it's user error. There is a line on each bag that says not to fill past. I have kept my items below that line, sometimes shoving and stuffing coats down below it. I have had ZERO issues sealing a single bag. The white clip starts it off, and I followed with my fingers, snapping it closed more. You definitely need to use your fingers after slowely swiping the clip. It's just like a ziploc bag, and very simple. Then I got my vacuum and sucked it all down. It was amazing how much air it took out of some of this stuff. I had even watched videos on YouTube and was still amazed. I bought these because we are moving internationally and needed to fit heavy coats and winterwear and blankets and such into air crates to maximize the space (weight did not matter to us, if weight matters, be careful, it's shocking how heavy this stuff is when the air is sucked out!). They have now been compressed and sealed almost a month and I have not had a single bag leak. I have not unpacked one yet, and if something is wrong when I do, I will come back and adjust my review, but right now I would say these do exactly as they advertise if you use them properly.
