I have both MiMi and the Bimini. I love both of them. I prefer my Bimini. The vibrations for Bimini are strong, a solid 4 Vrooms. MiMi is also strong. Bimini is on the smaller side, so if you want a smaller insertable vibe, then this is for you. If you're expecting for the clitoral part to work miracles, it won't, but it's something.
Everyone's going to tell you to get MiMi. It's a good toy, but I personally think there are better Clit vibes out there. The we-Vibe Tango, Salsa, and Touch are all strong and have the same qualities except the first two are plastic.
I don't think you can go wrong. G-spotting is also nice with Bimini if you want that. The Curve is present but not overdone.
