I love the adjustable nature of these. I used to have cheaper plastic bottles ending up all over my drawer or bag from spilling out of the bin. I can take this little bag with me when I travel and I don't have to worry about what size I need or what shirts to take with me. I use it almost every day and am completely satisfied. My only minor complaint was that the inner plastic shell doesn't seem to stick to the outer case with friction, so I had to glue it in place to keep it from popping out at times. It doesn't matter much, but it's happened enough times to compel me to resolve this issue.
