This was a welcome gift. As I read initially, there is a bit of a learning curve. But the alternative sensation seems to penetrate more deeply in the right places
I've had the Sona Black for about a month & each time I use it, I find a new way to experience pleasure. Each of the 8 vibration patterns unlocks a new sensation. And the ability to adjust vibration strength makes this product perfect for any mood I'm in. Whether I want it slow & sensual or fast & intense...Sona Black has me covered.
