We love this thing!  It's very well made, sturdy, handy, small and light enough to keep in outer pocket; quick, simple and easy to use.  What more can you say!  You can secure your bag or jacket to your luggage with it.  Could be used with rolling coolers that have a handle, as well, to hold that rolled up beach blanket or smaller picnic basket.  While, it might not fit a 29" upright suitcase with a short handle quite as well; it sure fits everything smaller.  Make sure the luggage hand grip you plan on attaching it to is firmly attached to your luggage, if you are setting a heavier item on top.  Good investment, will buy another for my spouse!
