Can anyone tell me what the specific differences are between the Jopen line's Vr7 and Vr10, Vr11, and Vr12?

I have seen and held the Vr7, but not the others. I can see that the end is different, and that the shaft of the Vr7 appears to be smaller both in length and width, and that the small arm/ear portion of the vibe seems to be a somewhat different shape, and that the Vr10, 11, and 12 have a couple little ribs in the middle of the shaft.

And of course, the Vr10, 11, and 12 come with the little charging port stand thing.


Are there any other major differences? I saw a video somewhere where a girl was showing how you can adjust the flexibility or degree of rotation on the Vr10, and it didn't /seem/ like you could do that with the Vr7. Is this true? Are the vibrations different? Fewer settings? In terms of actual functioning?

I've also heard the silicone for some reason is different on some of the Vanity line, like the Vr3 apparently is more of a lint magnet than some of the others, or something? What have your experiences been with the Jopen silicone in that regard both with these toys specifically as well as any others in the Vanity line you may own or otherwise have experience with?
