Honey Play Box - Harmony Duo - ストラップレスストラップオン（アプリ連動）

The app control is what sold me and it actually works smoothly from across the room. The shorter shaft staying put with pelvic floor muscles took a bit of practice, but once I got the angle right it was hands-free the whole time.

Held in place better than I expected once I got the angle right, and the app control actually worked without dropping the connection. My only gripe is the hollowed end takes a bit of maneuvering to line up comfortably on the first try.

The app control is handy but drops the connection if my phone's more than a few feet away, which gets annoying. The contoured shaft holds fine with the pelvic floor muscles once it's in place. It works, just not as smoothly as I hoped for the price.
