I was really looking forward to using these bags, since I travel often.Pro: decent materialCons:-each bag was individually wrapped. Yes, all 16 of them. It is not only extremely wastefully, it was also very very annoying and time consuming to open every.single.bag.-NONE of the bags were labled size wise. So after spending all the time unwrapping every bag, i then had to spend MORE time holding every bag up to see what size it was, and put in piles?♀️-They did not come with any directions, and I have never used this kind of bag (non vacuum). So I had to spend EVEN MORE time trying to find directions online.-The topper was that after doing ALL of this, the zipper part came off of 3 out of the 4 bags I was going to use. And only 1 bag actually had stuff in it, the other 3 I was just opening them so i could use them.-I originally gave them 2 stars, because the material of bags are decent. But I emailed the company about ALL the problems I had with their product, (I always give companies the benefit of doubt that maybe I just got a fluke product. And I like to give them the chance to make things right) but they did NOT respond.My conclusion- crappy product and crappy customer service.
