So far, so good!
I tried U-Lace because I have had 2 years of frustration with Hickies (a competing product) breaking about every week. I have concluded that Hickies elastic "loop" has a design flaw where the eyelets cut into the loop causing the laces to break. U-Lace has an alternate design concept and elastic material that so far has bee very reliable. I am hopeful. Time will tell.
