Small, discreet & adorable
This is a very discreet little toy and I really enjoyed it. The fact it comes in a compact pouch - with all the accessories makes a purchase like this- a no brainer…. It's easy to use, small, doesn't actually look like a sex toy- so I don't have to hide it for dear life. It's easy to set up- chargin...

If diamonds are a girl's best friend, this little gem just stole the crown 👑. The Cosmopolitan x plusOne Girl's Best Friend Vibe isn't playing around—this thing is powerful. I'm talking "why waste time when you can hit the O in just minutes?" powerful. The design is sleek, it feels luxe, and it doesn't take much effort to see (and feel) exactly why it's named after jewels. The vibrations are deep, consistent, and honestly… a little addictive. I thought I was going to just "try it out" and ended up grinning like I just won the lottery. It's quiet enough to keep things discreet, strong enough to keep things interesting, and the fact that it comes with a storage bag makes it feel like the VIP of toys. Bottom line: If you've been on the fence—stop. Add to cart. Your body will thank you, your stress will vanish, and you'll wonder how you ever lived without it. 💎 This gem is the real deal.
Packs a powerful punch!

This little "gem" has so much potential! There are several different speed settings. It's easy to charge, easy to clean. It has a comfortable grip and the noise is subtle.
Small but mighty!

It's not as big as I expected, but it is definitely effective. Good things come in small packages. Not over powering like some. Not loud, so you can be discreet if need be.

The Cosmopolitan x plusOne Girl's Best Gem Vibe feels like the kind of chic, playful accessory Cosmo would have spotlighted in its OG heyday—sleek, jewel-like, and designed with a fun, flirty edge that makes it as stylish as it is functional. The design is compact, colorful, and easy to tuck away, with smooth lines and a polished finish that give it that "treat yourself" vibe. True to plusOne's reputation, it's thoughtfully made with user-friendly features, whisper-quiet operation, and quality materials that make it durable yet approachable. While it doesn't scream high-tech gadgetry, its charm lies in being simple, practical, and confidence-boosting—like a little gem that adds sparkle to your self-care routine.

Umm yes please. This thing worked. My partner used it on me during sexy times and when I say I came so hard, I mean it. This little jewel is, well, a jewel. 11/10 will be using this regularly. Good job team.
