Works great, very easy to set, stronger than the standard travel lock shackle.  One suggestion is to design in an indicator to show if it has been opened, but that is likely in the works.  Some others rated this lock for other uses than travel and I feel its intention is for luggage travel security; TSA means it is made for travel, not foot lockers and gym bags.  You can order a 1/4" shackle model for larger hasps. I recommend this over any thin shackle type, which break during travel and can be easily cut or twisted open with pliers. This is secure and flexible.
