Fixing the Fatal Flaws of the Fitbit Flex Clasp

Does Your Fitness Tracker Need a Security Band?

Many owners of the Fitbit Flex, struggle every time to put it on securely. The band clasp has a nub to force through slots in the band, and it is very tough to do one-handed. Unless you are Lady Mary and have a maid dress you in the morning at Downton Abbey, it just isn't worth the struggle.

Owners of the Flex and various other fitness bands that lack buckle closures are also complaining that not only are they tough to close, but they are losing them when they fall off unobserved. You can imagine sidewalks littered with flocks of fallen and forgotten Fitbits.

Preventing Losing Your Fitness Band Due to a Loose Clasp

Now an entrepreneur has come up with a stylish solution - the Bitbelt. It's a simple silicone sleeve that you slide over the clasp to keep it secure. You can mix or match colors. They have sizes for the Force and other larger fitness bands and for the Flex and other smaller bands. 

Many other manufacturers have jumped on this bandwagon, so you may see similar fasteners sold alongside fitness bands at the big box stores. Even better, you can buy bling for your Fitbit and other trackers that will make them fancy as well as more secure.​

Do-It-Yourself Fitness Band Security Solutions

Heart Disease Expert Dr. Richard Fogoros sends this solution that will prevent losing your spendy Fitbit. Head to the hardware store or plumbing store and buy a pack of o-rings. The #41 o-ring is the right size for the Fitbit Force, but you'll need a smaller size for the Fitbit Flex. That should only cost a dollar or two and is cheap insurance for losing a fitness band that costs $99 - $129. Just slip it over the clasp to keep it secured. He says it is comfortable to wear and unobtrusive.

The Misfit Shine sportband solves this problem by having you thread the clasp first through a loop on the other band, so if it comes loose, that loop helps retain it. Fitbit hasn't yet provided their own solution for the Flex, Force, or Charge, but the Fitbit Charge HR has a standard buckle for secure closing.

How Do You Get a Secure Clasp Closure With the Fitbit Flex?

This won't solve the initial problem of not having a Mr. Bates or Mrs. O'Brien to assist you in putting it on in the first place each day. A solution can be to place a dime, penny, or other thin solid object under the clasp next to your skin. Then when you push on the clasp to close it you have a hard surface to press against. This makes it easier to get a good closure.

If that still doesn't work, you're going to have to break down and ask your spouse, kids, roomie, or random strangers to help you get your Fitbit on securely. Maybe you need to never take it off? Alas, that is not recommended, you need to wash underneath it regularly to prevent wrist stink, rashes, and even infections. While the Flex is water-resistant, it isn't recommended that you shower with it, plus you need to take it off to recharge it every few days anyway.

Frankly, my solution was to buy the excellent Fitbit Charge HR instead, with its buckle clasp that is easy to put on, take off, and wear securely. And no sooner than I bought that then I fell in love with the Apple Watch and switched to that.
