Made with both metric and imperial tick marks, the Inch Perfect vibrator lets you control exactly how deep your loving goes. There are two models, the nine-incher and the six-incher, and costs 14.99 pounds ($28) and 9.99 pounds ($19) respectively. What's the point of this? Well, perhaps you don't want to use up too much, get accustomed to it, and subsequently leave your husband because he doesn't measure up? Not that we know this from personal experience or anything, but...yeah.
