FINALLY got an email that my adapter was shipped today (8/25)! They sent an email a while ago that they were having trouble getting a supplier to make the proper spring bars for the adapter, and it would be at least another month before they shipped. I had the option of getting the adapter without the spring bar and using the ones from my current watch band or waiting. I took the first option because who knows how long it will take to get the spring bars, plus I'm tired of waiting!
I don't know when the adapters will arrive, as the tracking number isn't active yet. Probably take a while, but at least I know they're on their way! Will post my experience with them when they finally get here.
