In the past 4 weeks I have gone from none to 4 due to the great sales. I have found out that I love them. The amethyst, Blossom G (review is up), Red cyclone, and the Love one. Get the cyclone for free right now with purchase and try it. Then you wont be out any money.
It is a totally different sensation and I am impressed. That is probably why they sell so many. I have found several more to put on my list.
I also wrote a review on Reflections Hope, a glass vibrator. It has become my favorite toy. Its a glass vibrator and I feel that the glass conducts the vibrations better than my silicone, or jelly toys. Check out the reviews.
good luck with your exploration!
