I recently made an impulsive purchase of a Fairy Mains Powered Massage Wand while shopping at one of those warehouse-capacity electronics stores. The thing turned out to work great on my muscles when they are sore from working out (or just from getting old, I imagine). It is so powerful that after using it on “high” setting then shutting it off, it takes at least a full second maybe two for it to stop vibrating.

Fairy Mains Powered Massage Wand Review
My biggest issue with it is the size and weight. That limits the positions where I can comfortably use it. Along the lines of your observation about the intense vibration of these kinds of devices, I only use the Wand on low. High doesn’t feel good to me at all as it makes me numb within about 10 seconds and I haven’t learned to orgasm that quick yet! On the low setting, I like how deep the vibrations are and that allows me to stimulate my clit without putting the vibrator right on it, which is an issue for me as my clit is very very sensitive. This allows me some ability to build my orgasm up slowly without over-stimulating myself. I do have to do a little maneuvering with my other hand, though, because the vibrations are so deep, it actually makes my labia tickle and itch (and not in a good way). I usually place my other hand right at the entrance to my vagina and that keeps the itching from happening.
As mentioned above, the biggest downside for me is the size. I do a lot of orgasming on my knees and the Fairy Mains Powered Massage Wand is just too big to comfortably get up between my legs and not be bumping it into the bed, floor, or whatever I’m kneeling on.
What we probably use it for the most is during scenes where Hubby is driving the vibrator and making me orgasm. With the vibrations being intense and deep, he can get me to orgasm without a lot of finesse, which he struggles with when using our smaller vibrators. As long as he doesn’t over stimulate my clit and get me jumpy, an orgasm is a sure thing with the Fairy Mains Massage Wand.
