The Nanovibe Finger Vibe is a small disposable vibrator encased in soft Thermo-Plastic Elastomer with a ring/loop designed to be worn on a finger so you need not hold onto the vibrator during use.
Here is a small snippet from True Pleasures review of the Nanovibe Finger Vibe:
“The Nanovibe Finger Vibe is alright, but I don’t think I’ll be replacing anything when the batteries conk out. I’ve had better, and I prefer toys that stay with me for the long haul, not for a one-night stand. Above all, it’s better for the environment. There are way too many wasted sex toys out there and not enough recycling programs.”
