I am not going to use them any soon: they are spare ones for my spare sneakers and it's not even the season. With that said, they make quite a positive impression: they look good and feel good to touch. I like the casing too. I haven't checked the length. My primary concern is if they will hold the knots - this is why I bought them as shoes' factory laces are usually (very) poor. Tied one in the air - it felt promising, like not letting go easily when pulled. Thus I can't give the top rating before I've really used them but my anticipatory impression is positive.
