I have the Fairy Mini. I chose it because it comes with it's own travel pouch, and as opposed to the Hitachi which only has two settings unless you get the control converter, the Fairy line has varying speeds.
I want a pocket fairy cause of the size and the adaptability but I have the inspire and it's amazing. It sounds like a saw or clippers or something- I always have to reassure myself that despite its strength it's not going to hurt!! The hitachi maybe a million women's toy of choice but seriously there are not that many that need a toy THAT strong- just a toy stronger than most and the inspire certainly is that and it has several attachments
I have the Fairy Wand (the biggest one, which plugs in) and I LOVE it. It has a ton of power and I never have to worry about recharging it; generally I just leave it plugged in near my bed and it's no problem. I don't like the fuss of not always having a toy ready when I need it.
