Vibrating cock toys - solo play

Can anyone recommend a hands-free, wearable penis vibrator for solo play? The vibrating cock rings LH sell give the impression they are geared more toward improving sexual performance with a partner but I am looking for something purely for hands free solo play that you wear loosely on the shaft/head. I’ve tried the magic wand with male attachment but I find it’s too tight and too powerful so everything is over in seconds. I prefer a long, drawn out sticky build up. Sorry for explicits 🤭

I've yet to discover a penis vibrator that is 'truly' hands-free, but this one we got sent by Lovehoney (Tracy Cox Supersex Male Vibrator) a while back could be what you are looking for. You can definitely use this one hands-free to some extent; and the vibrations are fairly decent but not too powerful, so if you do want longer, drawn out sessions, then this might be for you.
