I was surprised at how strong this vibe is, it certainly is effective at its job. However, it is very loud, I could hear it outside my door, but only just in front of the door when the house was silent. I make sure I have some sound to make sure it doesn't draw any attention. I've also found that it has a big jump in the volume level when it hits the absolute highest, so I avoid using it when there's a chance someone could walk in. One other thing is that the o-ring used to make this waterproof is not big enough to let it be submerged, I found a few drops of water inside when I tested it, but it hasn't had that issue when I'm washing it, so it should be safe for shower use. Aside from that, it is a nice vibe, particularly for its low price and sheer strength compared to other in the same price range.
