This vibrating toy is intended to suction to the nipples and stimulate them with teasing nubbies inside the cups, accompanied by strong, rumbly vibration. I believe they will work well for anyone with nipples or another erogenous zone that may take well to simple suction cups! I actually found them to also be quite stimulating on my inner thighs. Placed there, they're a perfect tease! The vibrations are soooo close, and yet so far. Yummy.

These cups require no advanced knowledge or finesse, just the ability to turn a single dial and press suction cups to skin! A person of any body type or gender identity could easily and effectively use this item. Fun for all!

This is a very basic dual bullet with a hard plastic battery pack, plastic bullets, and soft seamless silicone cups with textured nubs inside. The texture can be a bit pokey, depending on how tightly you suction them, but I do think the nubs provide extra stimulation when positioned well. You can easily remove the cups to clean them or to use the bullets on their own, without suction.

This design is not discreet at all and is bulky to store. It toy consists of a large, flat, smooth battery pack with a tiny dial in the upper righthand corner. It is a bright, wisteria purple. Its cord splits to two strong vibrators at the ends, tipped with removable, palm-sized suction cups. The cups are very simple to apply and remove and offer a very mild suction, complimented by strong vibrations.

The cord was long enough to reach my own hand, but depending on position it may not be long enough to hand off to a partner. The battery pack is huge. I am a tall woman, with proportionately larger hands than many more petite folks, and holding the pack was not comfortable for me. I found it to be heavy and cumbersome, having to reach fingers or flip the pack around to reach the tiny, strangely located dial way up in the upper right tip of the pack. I think that a button style design would have served better than the dial, especially with its odd placement on the pack. My thumb naturally falls at the center of the pack when I hold the control pack, where buttons could have been conveniently located!

I was pleasantly surprised by the effectiveness of these suction cups. My breasts are a C-cup with quite small nipples. It worked perfectly for me, though I cannot attest to how it will fit other bodies. The cups may take a couple of attempts and a bit of practice to suction properly on your body. If you suction too tightly, the stimulating nubs inside just poke your nipples, instead of tickling and teasing them! I also found that position matters. The force of gravity combined with the motion of vibration or penetration is more than enough to knock the cups loose. If you're lying on your back, they're far more likely to stay put.

The dial controls have simple instructions. Up is on, down is off. With three AA batteries, these vibrators pack a punch, even on the lowest setting! You can choose exactly where you want the vibration strength with the adjustable dial. Batteries are easily replaced with a sliding door on the back of the control pack.

I would actually have really liked if the vibrations started off at a lower setting. This kind of toy is meant to tease. It would be nice to be able to begin low and ramp up more slowly. I would also have deeply appreciated some patterns! Pulsation patterns are perfect for teasing and toying with nipples.

Caring for this toy is quite simple. It is not waterproof, but you can easily remove the silicone cups and rinse them off with soap and water, cleaning between the nubs, or boil them to fully sterilize if need be. I've tossed them in a drawstring bag for now, but I'm a bit concerned about whether or not the silicone cups will distort over time if they're squished during storage.

The toy comes in a very simple, small cardboard box. I don't recall a user's manual inside, but there is some basic information on the box.

These surprised the hell out of me! I was incredibly skeptical, as toys of similar design and intention are often gimmicky, poorly made, and worthless in practice. The first time I tried these, I was shocked. They feel fantastic. The vibrators are strong and even on the low setting they send a delicious charge right between my thighs.
