Review on 🔗 Industrial Twist Ties - Twisted Goat Heavy Duty and Reusable Gear Ties for Securing Cargo, Transporting Goods on Roof Rack, Hanging Hammocks, Organizing Camping Gear, and More! (3 ft 4 Pack) by Tony Conlon

This is an unreliable method of securing your belongings on top of your car (as advertised). No matter how tight your zip ties are, your materials will slide, move, and bounce around a lot. This is probably more likely if you're dealing with metal trunks making contact with plastic on the bars. I tested it during a test drive on a desert road and my Hual was about to break free (thankfully I had taken other measures to ensure it didn't come loose). but I will not trust him in a transport situation. I'll just glue a pretty tie. Will return.
