I was very excited to receive these. However when it was time to pack, it became apparent quickly they took up too much room in the suitcase. I was able to get ALOT into them, but when you compress them, the top and bottom become rounded and they do not stack properly (or allow for loose items to stack nicely). I ended up just using 2 of the compression bags and the laundry bag. I did not have issues with the quality- it seems good to me. You have to run your finger along the zipper when using the compression because it will catch the colored fabric liner (I have experienced this with other compression bags too, I think it's just the nature of them). I will definitely use these bags, but they did not serve the purpose I bought them for. I wanted to compress sweaters to make more room in the suitcase. I was able to pack more without the bags.
