This is an excellent toy if you want more than your average stimulation!
The first part of the toy that fits into the vagina is around 4 inches long, just a little below average size. The circumference is around 3.75 inches. This part of the vibe vibrates the whole length on many different speeds. This part of the toy also has three larger beads on it. These help stimulate you as they move in and out. They rub against the vaginal opening, making you expand and contract around them. It feels wonderful, along with exciting you even more. It feels as if there is a constant entering and leaving, almost like you're using two different toys.

The second part of the toy generally is used to stimulate your ass. This part is around 3.5 inches long, just right for what you'll need. The circumference is around 3.5 inches also, not too big and not too small. This part of the vibe also vibrates down the whole length on many different speeds, allowing you to go fast or slow. On the highest speed, the vibrator can be quite powerful. You need to test it out to make sure you get exactly the right speed when you want it; definitely a good idea if you've never used a toy on your ass before, as it can be a bit uncomfortable if the setting is too high.

The part of the toy used for the vagina can be moved separately from the part used for your ass, so you can move one while keeping the other stationary.

The handle for the toy is around 4 inches long and 6 inches around; excellent for being held in your hand or your partner's. A tiny bit of awkwardness can be experienced by you or your partner the first time you try and use the toy, especially if you're not prepared for it. Things get much easier as time wears on, though.

I also noticed that you can use the anal stimulator to insert in your vagina and use the vagina stimulator on your clit. This works excellently for your clit and stimulates your vagina equally as much. Using this part on your clit works extremely similarly to a rabbit, and is most enjoyable with the vibration on high. This may be more comfortable for those people not ready to venture into toys for their ass. The option is there, though, if you feel ready for it.

I would describe the power levels of the Scorpion slightly above average with enough power to get the job done for most. Both dildos are controlled by a single motor, so it's not possible to have one set on low and the other on high. This toy has your basic control dial on the end. Using a toy like this is easier than trying to control two separate vibrators at the same time. No worries here about one slipping out while you're holding onto the other one!

The Scorpion is made of rubber, so it's porous. I recommend using condoms for that reason. I wash this toy before and after each use with anti-bacterial soap or any type of toy cleaner.
