I watched the video & followed the directions. I clipped the laces 2&#34; & applied the doohickey as shown. But a coupe of days later it came off & I didn't notice until I took them off that evening. So I don't know where I ost it or how it came off, & 1 of the lace ends unnraveled about an inch so even if I got another thingee, I stil can't use the aces now. And I loved the purple ones SO much!.
