The Crystal High Intensity Mini vibrator surprised me with such power from just 3 small watch batteries. While this vibrator's primary function is that of a clitoral vibrator, it also can be used to tickle and tease the nipples, breasts, inside of the legs, or anywhere else you can think of. This little technological marvel is 100% waterproof so bathe and shower away while enjoying the vibrations. With the toy being completely waterproof, comes the ability for internal play. While I guess you could insert this into the vagina or anus, there is no easy (or even a hard) way to remove this toy, so I would strongly advise anyone not to insert the Crystal High Intensity Mini. Anywhere.

The toy is made of simple but effective hard plastic. This is part of the reason that the vibrations are so surprising: the harder the material (generally) the better the transmission of vibrations. Plastic is non-porous and phthalate-free so it is very hygienic and easy to clean with a little soap and warm water.

This little rocket of a vibrator is 2 and 1/4 inches long and 5/8 inch wide. One half of the vibrator is completely smooth and seamless, perfect for clitoral stimulation. Just behind the halfway point there is a ring of 6 tiny jewels set into the vibrator that give it the name Crystal High Intensity Mini vibrator. The back third of the vibe is made up of the cap, which it seals in the batteries with an o-ring and has the one-button vibration control on the end. All in all, a very simple but effective design.

The controls on the Crystal High Intensity Mini vibrator are very basic, but that is a good thing. There is a simple button on the tail end of the vibe that you push to turn it on. If simply clicked once (pressed and immediately released) the vibrator will turn onto its slowest (and weakest) state. Holding the button down, whether it is from an off state or at any point during use, causes the power to slowly ramp up until it reaches peak intensity.

The button is actually back lit, and during the increase, the button back light blinks at an increasingly faster rate until it stays on at full power. You can let go of the button at any time during this "ramp up" and the vibrator will stop increasing and hold its level, so the level of vibrations are essentially infinite. That being said, most people will need the maximum level to make this worthwhile.

My wife, while by no means having the "clit of steel " that I hear about elsewhere on this site, likes her vibrations with some oomph. I am slowly learning that in reviewer-talk she prefers the rumbly ones to the buzzy, and this toy is as buzzy as they get. Her favorite toy is the Hitachi Magic Wand, if that gives you any idea. So for her, this little toy, while fun, just didn't do very much more than what she could do with her hand. So as far as the use, it was a little bit of a bust. This toy is, however, still used during foreplay with relative frequency, so it doesn't go unused!

Being plastic and 100% waterproof, this toy is easy to clean up. Simply use a little soap and warm water and you are as good as new. Plastic is non-porous and phthalate-free but I would not boil this as A) you will harm the inner electronics and B) the toy is not meant for any use that could really even need absolute sterilization after use (such as anal play). As with all vibrators, you should remove the batteries if you plan on storing it without use for more than a few weeks. Other than that, this toy is easy to use and a breeze to maintain!
