A cock ring with light settings — awesome! The packaging is a hard cardboard fold out showcasing neatly all the functions of this ring. Key notes are the 2.3" diameter, silicone and usage time of up to 100 minutes. There is also a guide to which colors represent which "mood.”
The inside guide I mentioned is a color representation of the vibration setting you are currently using. Red being "Tender Rhapsody" and the blue being "Elevating Ecstasy.” The ring itself functions amazingly. It's not too bulky and has a good stretch to fit snugly. If you need a cock ring, this one will work wonders. And, if you want to multi-color strobe a dark room … Jackpot!
