Review on 🔒 TOJWI Non-Slip Gripper Zipper Pulls by Amber Perez

My trusty Northface backpack has lasted for over a decade, unfortunately the zippers fell off years ago. I figured it would be a better solution than zip ties. I haven't had them fall apart yet (like some of the other reviews) but can't get them to stay zipped. If I put them through a hole in the zipper, they will come loose if I pull the zipper in that direction. When I tie them to a zipper, they unravel and fall off after a few days. They might have stayed if the string had had more grip or if it had been a different material with more friction. I have given up this product.
