The function of the Vr7 is very easy to control. The Vr7 is controlled by two buttons that are one the handle of the vibrator. One button controls the shaft of the rabbit and other controls the clit arm. The top button on the handle controls the shaft of the vibe, this causes the shaft to rotate in a circular motion. The rotation starts off in a slow motion and when you hold down the button it starts to spin faster.
The faster spinning isn't super fast and out of control but if offers a more swift motion to rub your g-spot. This is perfect for those who need a quick swift motion to stimulate the g-spot more than a slower stroking motion. When the shaft is inside of you and you squeeze it using your vaginal muscles this does NOT stop the rotations. This will allow you to practice working on your kegels if you choose.
The second button that is right under the first controls the clit arm. The clit arm doesn't move at all but the vibrations are extreme! When I say extreme I mean it. The vibrations are very strong so if you are into super strong vibrations I highly recommend this to you. The clitoral arm doesn't really have a low setting it's starts off at a high. This can be a problem if you want this but can't take extremely strong vibrations. You really have three options high, higher, and extremely high. This is perfect for women who have "Clits of steel".
The neat part about the Vr7 is that you can have one on without the other. You can have the shaft rotating and the clit arm not vibrating. You can have the clit arm vibrating and not the shaft rotating. This is neat because a lot of rabbits don't have this option. The buttons also have a locking mode so you don't have to worry about the vibrator turning on by mistake during travel or in storage. You just have to hold down the button for about 4 seconds to lock it, and another 4 seconds to unlock it. When it's locked the buttons will flash and it will do this again when it's unlocked.
When turning on the Vr7 you just have to press down the button one. When changing the setting you have to hold down the button for a few seconds. If you just press the button without holding it down will turn the vibrator off. The button will light up each time you press it. When you hold it down and reach the highest setting for either the shaft or clit arm, the buttons will flash quickly to let you know it's at its highest.
The Vr7 is a recharge able vibrator, when you first receive the Vr7 it's completely dead. You will have to charge it before you can use it. To completely charge the Vr7 it will take 3-4 hours. This is the only toy that I have that needs that long to completely charge. One charge for me personally can last about 4(30-40) minute session. When the Vr7 is charging there is a red light around the charging port that lights up, when it is done charging the light will turn off.
The Vr7 isn't too loud, you can hear it a little through the covers in a silent room. but you can't hear it through a closed door. The sound you do hear sitting is pure silence is more of the motor of the two motor wining, but the sound can be drowned out. When used in the water the sound is the same and so is the vibrations. You don' have to worry about the vibrations decreasing when submerged in the water.

Thanks for the video and all the info
