There are only two buttons on the Vr3. There are dual motors and one controls each motor. One motor is located in the internal shaft and one is located in the clitoral attachment. The top button controls the internal motor. Simply press it once to turn on and hold it to turn it up. It's hard to say how many levels of vibration there are since it's press and hold and not press once and press again. It's a constant hold. The bottom button controls the clitoral attachment and works the same way - press and hold. To turn either one off you press the button once. The only bad thing about the control is that there is no way to turn it down. It's up or off and that's it. It doesn't really bother me so much because I usually work my way up to the highest settings and leave them there but if you like to vary between the two it might be an issue. The great thing is that it turns off in less than a second. If you need to turn this off in a pinch, you're in luck. The buttons are easy to press during use where I (for once) didn't have to take the vibrator away from my body to change the vibrations. They are located where I hold the vibrator but I didn't accidentally press them when I used it. Some people have reported differently. I did accidentally press them during cleaning. It does have a lock feature, as mentioned. Simply press and hold both buttons for four seconds to lock.
The vibrations are located exactly where they should be for each motor. The vibrations for the shaft start in the middle of the shaft and work their way to the tip. They are pretty constant through this area. The clitoral attachment are focused at the tip with some of the vibrations radiating downward. Neither of the vibrations reach the base so you're hand will not go numb during use.
The vibrations on the shaft start at a very high level two and work up to a very serious level five. They're so powerful that I found the width of this vibrator ended up feeling twice the size of what it actually was because it was vibrating so much inside of me. The shaft has deep, rumbly vibrations. Not the deepest pitch ever, but pretty close. They feel absolutely wonderful internally. The clitoral attachment is not as strong as the shaft. It starts at a high level one vibration and works its way up to a high level three. The clitoral attachment is buzzier than the shaft but not as buzzy as a bullet. I'm not able to orgasm from the clitoral attachment alone as the vibrations are not strong enough, but the combination works well. I wish the clitoral attachment has vibrations that matched the shaft vibrations. Two level fives would have been a great added bonus to this vibrator.
There are no patterns to the Vr3. This could be a good thing or a bad thing depending on your preference. Considering my hatred of all things pattern, I'm over the moon that they weren't included on this vibrator. No worries about pressing too far and ending up with a pattern and having to go backwards or cycling all the way back through. Steady vibrations all the way. This could possibly be one of my favorite things about this vibrator.
Vr3 is virtually silent even on its highest setting, a big deal especially considering how strong it is. I can barely hear it when it's sitting next to me with no covers and the sound can be almost completely dissipated with covers or a closed door.
While the port does not close up, the Vr3 is waterproof. I didn't trust this at first but a submersion test confirmed that it is, indeed, a waterproof toy. I still probably wouldn't take it in a tub because I'm a super paranoid person but I think you would be safe if you did.
As a rechargeable toy, the Vr3 will require three hours of initial charge before it's ready to play. It hooks up from a port located at the bottom of the toy. It glows red while charging and white when fully charged. I have yet to lose my charge on this after initial charge and I've been using the heck out of my Vr3. I've gotten hours of use out of it and I'm still waiting for it to die on me.
