Sync O

The O-shaped internal arm actually stays put during the whole session—no constant readjusting like with other toys I've tried. My partner and I both felt the vibration clearly, which made for a surprisingly connected experience. Definitely worth the splurge for how secure it feels.

The flexible internal arm really molds to your body, so it doesn’t slip even when things get moving. We’ve used it a few times now, and the shared sensation is way more intense than I expected—it’s become our go-to.

The C-shape stays snug even when we switch positions, which is a relief since I was worried about it slipping. I just wish the app syncing was a bit more intuitive to set up the first time, but once it's going, the shared sensation is worth it.
