Query: Leash Works Well but is Unnecessary

I purchased this leash at the same time I purchased a Omron HJ-151 Hip Pedometer, based on Amazon reviews of the pedometer suggesting that the pedometer clip was weak and tended to detach from belt/clothing, and that a leash was necessary to ensure the pedometer wasn't lost/broken. I figured what's another $2 and it saves a separate shipping charge if I buy it later.The leash does work well, securely attaching to a belt loop via a metal clip and to the pedometer via what appears to be a medium-strength string loop.However, in my experience, the pedometer clip itself attaches very securely to my belt/clothing and the leash is unnecessary. Since I have already purchased the leash, I still wear it; but, with hindsight, I wouldn't have purchased the leash until I had worn the pedometer and possibly decided it was necessary.
