I am admittedly satisfied by this product, but find it to be very inconvenient given its size.
The vibrations are rumble-y, pleasantly so, and are good for a lengthy warm up, but I find it lacks in terms of presence when it comes to cresting. If you are used to something a little more focused and/or the Magic Wand, you may find this takes time to settle with. Finally, I think I have. Luckily it comes with a variety of programs, is really quite powerful, and, comparatively, very quiet.
I definitely recommend this as an addition to anyone’s collection, though I would not rely upon it as your sole means of...
(The cordless aspect is great considering it works well for slow build up and you can keep it on for quite a while.)
In a more conventional capacity: I tried this on my shoulder blade after pulling a muscle at the gym, and it was far more comfortable than Hitachi’s wand given the many programs and different strengths I could set it at.
