This toy, with 10 settings and a high vibration level at 3.5 bees, has a lot going for it. It's also waterproof, silicone, and pretty darned quiet. On the other hand, the lower settings make an AWFUL whining noise and when you turn it off it turns back on to the NEXT setting. The design also wasn't quite as effective at g-spotting as I would have hoped, but it's great for external use.
