The Shakers Vol. 1 is a one time use masturbation sleeve/onacup. It is basically a cup with a TPR insert you insert your penis into, do your business, and throw away. The Vol 1 Shaker is supposed to be the "virgin". It has internal nubs and ribs for added stimulation. It also has a tiny hole on top that you can cover with a finger to create suction. This toy is great for anyone who wants a different masturbation experience.

The outer cup is made of plastic. You twist off the lid, insert lube, and go. There is a foam lining around the edge of the cup that quickly falls apart which extended or rough use. When this foam starts falling off the edge of the cup rubs and causes pain. The inside is tight but not too tight and the nubs and ribs give extra stimulation. It is soft and squishy inside. This texture would be great for beginners and advanced users alike.

The lube included is awesome. It is very thick but not at all sticky. It was sort of messy but worked really well, a fair trade if you ask me.

The cup is just the right size to fit in the hand comfortably. It is small enough to be discreet to store, unfortunately though, the sound it makes while using makes it not so discreet. It is very loud to use. The interior is a great size for average men but may be too small in length for men that are larger. I would say anyone over 7" long while erect will not be able fully insert their penis into the cup.

It was tight but wasn't so tight that it was uncomfortable.

There is basically no care or maintenance required for the Shakers Vol 1 onacup. After you are done you simply screw the lid back on and throw away. You would probably not be able to rinse and reuse this cup (even if you wore a condom) simply because the foam that lines the edge of the cup wears away very quickly causing the edge to rub.

There is an amazing lube included but if you choose not to use it you can use a silicone or water-based lube.

The Shakers Vol. 1 onacup came in a clear, plastic box. It also included a packet of lube. There were no instructions but it was easy enough to figure out.

My husband had never used a masturbator before so this was a whole new experience for him. Something I should mention is that he is very set in his ways, he has his way of doing things that works for him so he is skeptical of anything new.

When we first opened the box we wondered how he would fit in this tiny cup. We kind of thought it would be larger. He did fit though.

I used it on him for awhile and I thought it was way easier on my hand to grasp the cup vs. his penis. After about 1 minute of use the foam started to come off the edge of the cup and started to scrape him. We tried adjusting everything and he held it at an angle that stopped it from scraping.

After he was done it was so easy to just put the lid back on and toss it. He thought the whole thing was kind of pointless but did say it felt good. Like I said though, he isn't a try new things kind of guy so that could be why he wasn't super enthused with it.
