First race I used it the lace lock fell off and I had to deal with a helicoptering race number for the bike and run. Made due and shoved the race number in my shorts...have had much better success with other belts that had snaps.
MUCH easier to use than traditional snap fastener belts. Sturdier & better looking, too. Only thing I don't like is that (as with all race belts) the strap hangs way over when tightened b/c I have a small waist.
