After I lost my first Garmin Vivofit because of the clasp, I received a replacement. I didn’t want it to happen again, so I ordered a three pack of the silicon rings. I installed one ring on my Vivofit, and it seems very snug and secure, so I am pleased with the purchase. On top of that, included with my order was an additional four pack of brightly colored rings labeled as a gift. It is great when a company exceeds your expectations.

I would also like to mention that Garmin replaced my Vivofit for , as a one time forgiveness offer.

this worked fine for my garmin vivofit. I know from experience how easily they can come undone this definitely helps.

I am ordering this ASAP! I have been using an "o-ring" to try to secure my Vivofit band, but it still opens up and falls off. In fact It fell off at the gym recently and luckily some nice person found it and turned it in! Actually I am surprised that Garmin is not offering something like this to Vivofit owners for free as the band is clearly very poorly designed for active wear.
