This is a great toy. Really! Its material is great, the buttons are easy to feel and use, it charges on the cool magnetic charger, it cleans off very easily and is waterproof! Great toy! It's got a cute shape, and it's texture is really pleasant. It's a bit stiff do to the mechanics in the center, but that's not a big deal.

It's got no notice as to when it is charged (that I know of, but I normally have my UFO charging)
No scent, no taste, it's silicone so it's safe for any body-part you want to mash it against repeatedly.

I had fun rubbing this toy on my vulva. I had fun enjoying the settings and vibrations-then I took it on vacation and could not, for the life of me, get it in when I wanted to. I tried multiple angles, relaxing, stretching my entrance with my fingers, in the shower, j-j-j-jamming it in! Nothing! Nope! Not happening!

I have no idea what happened, but this spoiled the bubbles for me. I did get off with it several times just grinding against it, but for the life of me I can't enjoy the insertable aspect of this toy. I am not at all certain whether it is due to my anatomy being stubborn, or the actual contours of the toy as each try had the same results, yet I could still manage FAR longer and girthier insertions without any issues.

So at once, the minivibe bubbles is an amazing toy but is a little too abstractly shaped as I've yet to find a comfortable way to get my kegels around it. As far as materials and craftsmanship, it's everything I want in what I would call a luxury vibrator. It may even be stronger than the UFO (that may just be the diffusion of vibrations though).

The minivibe bubbles is not a bad vibe at all, but it doesn't fit my body and mostly just causes me stress.
When I decided I didn't care if I could insert it or not, I had fun with it and could enjoy it as a surface vibe; it's strong and quiet and still has a very nice texture and drag.

Working well in tandem with the UFO, or even a regular dildo, the minivibe is nothing I would buy again, but it's got the makings of a very nice toy for someone.
