Gosh I don't have much to say about the Aneros toys - I had a partner once who was committed to finding out how to make the aneros work for him, but it never quite did.
He had a great attitude about it and loved trying, so it wasn't a frustrating endeavor. But yeah... they just never piqued my interest because of the ambiguously pleasant (but not earth-shattering) entertainment it seemed to provide. I know Zoey likes to introduce some folks to the aneros though and many men swear by the Aneros brand.
I also endorse the nJoy pure wand for prostate stimulation (seen here in a rather unorthodox mode of use) although to be honest, Im really into just getting my fingers in there. I have found over the years that my fingers provide some of the best prostate pleasure around. That said, I have these tiny hands and sometimes I need to use the Pure Wand simply because of biology and reaching the prostate.
