I purchased this for two trans-Pacific flights. Overall, they worked great, and we actually got a look of admiration from the pilot as he walked through the cabin.The one-way valve does make it a lot easier. I found it to be more comfortable to have it flush against the front of the seat so that my feet dangled off the end rather than as a true foot rest where my thighs and calves were left unsupported.
