This is a great vibrator! I personally love silicone, I have really sensitive skin so it's one of the only materials I trust. This toy is so easy to use, and really strong for taking only 1 AAA battery. The ripples and g-spot finder are really well designed. They hit my spots right, so I assume they'd be great for other women.
I didn't realize that the sleeve came off until I went to clean it, but it does, though the silicone is so nice I don't know why you'd take it off. This is a really quiet vibe too, and the size makes it perfect for me, I travel so often for work, that I just slip this cutie and a few batteries in my bag and I'm good to go. 5 Stars, and I'd definitely recommend it.
