I have to say this was my first real waterproof vibrator. It is purple my favorite color! It is a harder plastic with a soft feel to it. I was eager to try out my G spot stimulator. Battery insertion is a no brainer it has a tag in there to help you. (Thanks for the directions Mr. manufacturer it saves us lots of time!) It takes one double A battery you twist it open, pop the battery in, twist it closed and you are good to go. It is on the small side and easy to use. My one complaint is it is difficult for me to use solo. So I had to summon the help of my husband, which he eagerly obliged.....the vibrations from it were nice although I would have liked more control over the speed. It has an on and off which you control with a slight twist. I think I would have enjoyed it much more had their been a low, medium, high vibration control. I would definitely recommend this to anyone who is trying to find their G spot for the first time. This stimulator delivers on it's word of hitting the G spot.
