Battery Vibrators
Ah, the wonderful world of battery vibrators. A truly essential element to any modern Jill-off, the battery vibrator is now available in more shapes and sizes than there are birds in the sky. These are the most popular sex toys on the market because they are relatively inexpensive and come in every possible shape, size and color. If you've desired it, chances are they've produced it. And since customer satisfaction is job one, the number of battery vibes available has ballooned in the last few years.
different types of vibes, two vibe covers for the dildo-shaped vibe (to try different textures) and some lubricant so you don't get sore trying it all out!
One quick word of caution before you get hooked on these wonderful devices: it's not a good idea to use one battery powered toy for more than 30 to 45 minutes at a time as their delicate motors can overheat. The best way to avoid worrying about this potential problem is to keep at least 2 vibrators on hand at all times. Most women tend to find that variety in their vibrators allows them to achieve the best "O"s each time. With that in mind, if you're going to keep 2 or more vibes around, try a few different designs to see what tickles your fancy and to mix things up every now and then. Also, most manufacturers recommend using regular alkaline batteries with your vibrator (such as these Sony AAs, AAAs, and Cs) because high alkaline batteries such as Duracell and Energizer may also cause the motor to overheat.
With battery vibrators, strength of vibration is always an issue. If you've never used one before, it's almost always best to err on the side too much vibration. If you actually find the vibrations to be a bit much, you can just turn the dial to low or diffuse them through a towel. If the vibrations are too weak, then you're plumb out of luck. So, when choosing your first battery vibrator, take a look at the number and type of batteries required. The greater the number and bigger the battery, the stronger the vibrations produced. (There are, however, some exceptions: the single-AA Pocket Rocket, among others, is surprisingly strong.)
Another consideration is the location of the control dial. On many battery-powered vibrators, the speed control is located at the bottom of the vibrator, making adjustment during use awkward. If you're looking for a little boost at the moment of truth, you may lose your focus; fumbling around at the cusp of orgasm is never fun. There are other designs, such as that of the Emerald Screw and the iVibe Controller with Egg, that take advantage of a separate control unit which allows the user greater control of the speed and intensity of vibration. If you're feeling daring, there are even vibrators that are controlled remotely. The Remote Control Egg and Remote Control Butterfly can both be controlled from anywhere (or by anyone!) in the room.
