Great concept to have it hold little items like an extra quick link or valve core....except that they disconnect quite easily so you might lose those items.
Throw out your wimpy plastic levers--these are among the toughest I've ever tried, can handle even the tightest fits (and I roll with tubeless). Even better--they have built-in cavities to store a replacement quick link and even a chain pin. Great idea.
Highly recommend adding this to your out-on-a-ride kit.
Great for tri bike mini bag
Haven't tried them yet but I like the design.
