The Flash is a great toy. It's small, easy to hide and store. While it doesn't have much in the way of texture, it makes up for that with the functionality of it's vibrations. Given how it can be used to stimulate a woman or a man, I would think this one is best as a toy for couples to play with. You can make a game out of stimulating one another with it.

A Flash in the Pan
I think Fun Factory kind of dropped the ball with this one. The vibrations are nice and I like the patterns, they feel really nice... when I can feel them. The general area of my vag feels pretty pleasant when I've got the Flash inside me, but that's about all I can feel. To reiterate: The g-spotting part of this toy fails on two counts. 1: it's not long enough when inserted, and 2: it's curved away from my g-spot.
