For me, it does not stimulate the spots it was made for. However, the top fits perfectly against my labia and clitoris with no discomfort. For that reason, I love this design.
At first this toy is large. When used as a dildo, I found that slow was the way to go. A combination of the size and shape makes it awkward and painful to use rapidly. When use as a clitoral stimulator and somewhat stationary, the size is perfect.
This toy is probably better for someone who has already found their G-spot, or has a good idea. This was my first G-spot vibe - my "beginner toy". I have given up on it every finding it for me. I found a different but satisfying use for it.
It is not discreet. It's pretty obvious that it's some kind of toy. Though it can be concealed in a dresser drawer, toy chest or under a pillow.
It might be a bit large to take on trips. If it's your favorite toy, however, you'll find a way.
