I greatly prefer the Ina, primarily because of the type of vibrations.

The Vr3, in the shaft, is very throbby and wonderful, but the clitoral arm is ridiculously buzzy to me. The Ina, on the other hand, has deeper vibrations all around, with less of a drastic difference between shaft and attachment.

I have had both, and neither one worked out for me. That being said, Carrie Ann is spot on with talking about the clitoral arm. The arm on the Vr3 is really buzzy in comparison to the shaft which was a big disappointment to me. The issue I had with the Ina 2 was that it felt like it was clamping down on me the whole time. That won't be an issue for everyone though. I think the Ina 2 was better in general, just didn't work out for me.

Wish I could offer insight on the Vr3 but unfortunately I don't own that one.

I do own Ina 2 and I love it! POP is right about the clit arm, it does provide a lot of pressure which is actually what I need to reach orgasm. If you don't like pressure, then it probably wouldn't be the best option for you.
