I was hesitant to purchase these because of the price along with the mixed reviews I read. However, for a 2 week international trip I found they worked great! The plastic is thick enough that I was not worried it would break. I like how the bags come in a variety of sizes. They are easy to use and it is nice that you do not need a vacuum. I kept some clothes in there for the full two weeks, and even after the clothes do not have a plastic-y smell. Would definitely recommend! I am going to now use them to store summer clothes under the bed for the winter time.
I am actually really upset with this product. We bought this while we were out on vacation because we ended up with a lot more clothing items while out of state than what we took with us. It did not help make packing easier, the amount of items you put in the bag to get it to work was just a waste. I ended up having to go back another carry on suit case to take back with us since this did nothing for us.
The worst part is, I can't even return them because I "used" them and purchased them in another state.
I do not see these being helpful for traveling, unfortunately. Perhaps only traveling overseas for a long period of time? But short travels I would never use this product realistically. It would be more of a hassle. I received this product for free for reviewing it.
