This toy could be used by beginners and advanced users alike because of the ease and simplicity of use. Those looking for some advanced nipple stimulation/play may be disappointed by the lack of features, so it might be better geared towards beginners. The toy is designed to be used as a nipple stimulator rather than an "enhancer," but can also be used to vibrate any other part of the body you desire.

The nipple stimulators are made of silicone and are a milky color. The vibrating bullets are made out of metal and are silver. The silicone has a nice, smooth feel on the outside of the cup, and have long "ticklers" molded on the inside of the cup. The ticklers vary in length, with longer ones in the center of the cup that are surrounded by shorter ones, in order to create a different sensation on the nipple.

The stimulators are cup shaped and are 3.5" in diameter. On the back (outside) of the cup there is a channel in which to insert the included bullet vibrator - these bullets are about an inch and a half in length. The inside of the cup features the nubs, or ticklers which come in contact with the nipple. They are designed with two tabs on each side of the cup that are used to break the suction and pull the cup off the nipple (the box terms them "EZ-Release Tabs"). As far as the fit goes, these stimulators are designed to suction to your breast, effectively giving you hands-free play.

The bullet vibrators are easily controlled by a small button at the end that turns the vibrator on and off with a push. I would rate these bullets as pretty strong, and was surprised at their intensity. They are powered by three button cell batteries each- these are provided for you in the box, and they even give you an extra set of batteries for each bullet. Each bullet features one speed only, and there are no other controls than on/off.

The cup can be suctioned to the breast just by placing it over the nipple and putting pressure on it, pushing all the air out and creating suction (just how a normal suction cup works!). The tickers inside the cup are then situated perfectly over your nipple, providing stimulation and vibration.

This toy functioned pretty much like I imagined it would, but I got a little bored with it. The vibrations felt nice on my nipples, but I felt like I needed something more. It actually felt better when I had the cup "un-suctioned" from my breast and was moving it in a circular motion around my nipple- that way I got a lot more sensation out of the inside nubs.

The cups are made out of silicone, so it should be used with a water-based lube. They could be easily stored back in the original packaging.

The toy came packaged in a box depicting a woman on the outside (with a bra on), and a picture of the cups and stimulators. No instructions, but it was definitely self explanatory. The cups were sealed in plastic bags separately, as were the battery packs. Each bullet takes three button cell batteries, which were packaged together in a little column so you don't have to fight with each little battery separately.

The cups can be turned inside out easily and hold their shape - that way you have a stimulator that can be used on different parts of the body. I found that using them this way felt great on my clitoris, especially with the high-powered bullet.

I tried these with a partner one time - they stayed on for a little bit but we took them off - not a good idea if you have a partner who loves to stimulate your nipples his or herself!

I have D-cup breasts and found that the suction cups were a perfect fit and they held on very well. They also came off very easily with the pull-tabs.
