I thought this was an excellent purchase at first. However, once I opened it up and loaded the batteries in it, and turned it on; the first thing that happened as the feathers started spinning, was the biggest and fluffiest of the feathers flew off the top. Next, I attempted to let the feathers tickle my balls, only to have them get wrapped in my pubic hairs, like a drapery cord in a vacumn cleaners beater brush. Providing you have no hair where you apply the spinning feathers you might be ok. One thing though, don't put anything but the slightest pressure against the feathers as they will quickly stop turning. Regarding this products value as a vibrator, it is noisy and largely ineffectual in that capacity as well. I have a tickle fetish and I am sorry to say this product does not live up to the hype. However I am but one person. Perhaps your experience will be more favorable. -Bob
