I only have the Jopen Vr6 so I can't vote on this one. They look very similiar but I see the Ina reviews say it has patterned vibrations which is something the Jopen does not have. It all depends what you like. I really like the Jopen but in my review I thought the lack of patterns was a con for me (especially of something in this price range). Don't get me wrong I wouldn't give it up now but it does make me curious about the Ina as well. Enjoy whichever one you decide.
