Lights failed after a few weeks and had a replacement pair. The number of faulty pairs on eBay might show quality of the lights have diminished as our pair from 18 months ago still light up. Then the Velcro closure style is not suited to wide feet. Little one come home daily with shoes popped open. The elastic holds them on but the Velcro either fails to hold or because it sticks up partially closed and catches. Strap Velcro or the elastic laces without Velcro do a better job.

My nephew loves them. He's "quick as lightning now" and shows it off to all his friends
