I used my Chimmy strap to secure my hard-sided carry-on luggage for a domestic trip. I thought the strap did a fantastic job at keeping my luggage secure. I would highly recommend this for anyone who chronically overpacks like I do to the point where your zippers are busting open. The strap gave me that extra layer of security. When I tightened it it did not slide around and it stayed clean. I loved showing everybody at Midway and LAX that I support Jimin. Love it!
