The Waterproof Crystal Flex is one of my new best friends. It stimulates anally, vaginally, and the clitoris as well. Since it is so stimulating I primarily use it solo, although my partner does find it erotic to watch me use it as well. It's great for beginners because it is self explanatory into where everything goes; without being too big or bulky. Those who are more advanced with toys will enjoy it as well, since it does stimulate several areas.

The jelly material of the Crystal Flex is great for easing in and out, and because it is not a hard plastic, it does not overstimulate the clitoris too quickly. The texture of the bulbs (for lack of a better word) feel amazing when inside, without being too ribbed.

Since it is a nice size, I'd recommend this for either beginners or advanced users, depending on the mood of the participant.

There was not much of a smell to it once I had washed it once or twice. Originally, it had a bit of a rubbery smell to it, but not nearly as much as a harder plastic vibrator that I own. It was not a strong scent, so it did not detract from the eroticism of the experience.

I liked that the shaft would bend and stay in that position even after inserted. It can stimulate my g-spot, or I can keep it straighter and have it be more penetrating.

It's not overly large, and the shape makes it easy for both the anal beads and the shaft to penetrate simultaneously without much lube at all. The larger bulbs of the shaft, are a great design for stimulation.

Is this suitable for travel? Well, it depends on how big your purse is. It's quite obvious in what it is, so I wouldn't bring it over to the in-laws... it's not easy to hide, but it's easy to put in a drawer.

There are two vibrating bullets in the Waterproof Crystal Flex; one in the area which stimulates the clitoris, and one in the shaft of the vibrator, but it only has one control for the vibration so you can not alter the speed of the two separately.

It is not silent, but once inserted completely, and when held at the base, the sound does diminish some. I simply turn on my fan which is about the same sound, and make sure to use it under the covers if my roommates are home.

It is quite fun in the bathtub, and works well in the shower as well. Just make sure to tighten the base to make sure water does not get into the battery area, and you'll be wet not just from the shower!

This does require a bit of care, since there are three sections which need to be cleaned after use. I do use a anti-bacterial sex toy wash afterward, but could see using a spray as well.

When using the Crystal Flex I tend to be drawn towards water based lubricants. Since it does have so much stimulation, I usually do not find myself needing much lubrication once I have become stimulated.

Truthfully, it's small enough to place in my underwear drawer once it's been washed off, but would also consider putting it in my nightstand in case I felt so inclined to use it in the middle of the night.
