The Revolve is a beautiful aeronautical grade aluminum dildo that is cast in two separate pieces and then put together with a double sided screw and a rubber ring in the middle. The two pieces can be taken apart and and put seamlessly together with other toys in the Alumina collection. I have both the Revolve and Flow, both from the alumina collection, so I am able to mix and match the pieces to create one awesome toy that I just love.

The Revolve is 8 1/4 inches in total length. One end of the Revolve has a ball at the end that is 3 7/8 inches in circumference and a long concave section that is 1 3/4 inches in circumference at the smallest part. The other end has 3 balls that go from smallest at the end to largest in toward the middle of the toy. The circumference for the smallest ball is 2 5/8 inches, the middle ball is 3 1/4 inches and 4 1/2 inches for the largest ball.

To interchange two toys you simply turn to two parts and unscrew them. Once they are totally apart you will have two ends and a rubber ring and a silver double ended screw will be sticking out of one side, just continue to unscrew it until it comes out and you will have all 4 pieces. Do the same with the other toy and then reassemble with the two ends that you want.

When I got the Revolve, I also got Flow at the same time. I opened Flow first and saw a beautiful purple with a matte finish. When I got Revolve out of its packaging it has a shiny, glossy finish. The EF website shows them both matte, but the Tantus website shows them both shiny. So I think they are changing from one finish to the other maybe, and I got one of each. They are both beautiful matte or shiny, but I was expecting them both to be matte. Although, when I mix the pieces together and have the matte and shiny it looks pretty cool.

Although Revolve is 8 1/4 inches long, from my experience with the hard material only about 4 inches or so is really being used at one time. I tend to use the larger side, leaving the smaller section to function as a handle.

Judging by the paperwork and the information on the Tantus website, the alumina collection is intended to be a vaginal or anal toy. Because there is no flared base you want to be sure to use a partner for anal play, but it's certainly fun to use a partner for vaginal use as well. The one thing I want to be sure to remind everyone is this toy is metal and doesn't have any give to it at all. So when using it alone or with a partner be sure to take it a little slow. If you go a little too far it is easy to poke yourself or your partner, so please be careful. Also be careful with temperatures as well, you can burn yourself and you don't want a frozen Revolve sticking to your skin.

Revolve came in a slim black box with a sliver outline of the toy on the top of the box. Inside Revolve is encased in foam. I have been storing my Alumina toys in the original packaging because it is such a small box, but If you own more of the toys from this collection and you want to store them while they have switched out parts, you should store it in a padded bag.

Revolve can be cleaned with anti-bacterial soap or toy cleaner and rinsed with water. You can also boil in water or toss it in the the dishwasher as well.

Revolve can be used with all types of lubricant.

I'm not really big on alot of texture on toys, but I do enjoy the almost fluid movement that the Revolve creates. I especially love the combination of the large potion of Flow with the Large portion of Revolve.

Also, as these toys are made of metal they are kind of cold when you take them out to use them. Sitting in the air conditioning gives them a 'not too cold but cool enough to give a nice sensation if you enjoy cooling temperature play' kind of feeling. If you prefer not to have a cold toy, you will most likely have to warm up the Alumina toys before each use.

The Revolve is a great toy, although it doesn't get as much use as Flow, it still has its place in the toy box. It's the only toy that I own that has this bumpy shape and it's a nice change of pace.
