We have the PFun and the Pure Wand. My husband really likes the PFun; his only complaint being, it comes out during sex, as well as orgasm. He also loves to use the Wand on me, and I do so enjoy that. I prefer the Pure Wand (both ends) for anal play over vaginal play, but I have never been all that crazy about G-Spotting anyway.
Stainless is unforgiving. It can hurt, as Tim stated above, if you are over-eager. Do use caution and play gently until you get used to them.
We love the heat retention steel provides and their weightiness. There is something about not only feeling full, but heavy too. Anyway, we also like that we don't have to reapply lube very often because they are really slick all on their own.
We are hoping to purchase the Large plug soon. (We are on the fence about if we should get the large or the 2.0) ***Edited 2 hours later...bought the nJoy large plug tonight!***
The Eleven is certainly on my wishlist, and will be mine one day...when I have enough points (if I would stop spending them, it would be easier!)
