This is a half sized Hitachi with 80% of the power! Hitachi wands are the gold standard for what we think of as "powerful vibrators." Most Hitachi wands are over 12 inches long and must be plugged into a wall outlet while being used. But not this one! This 7.2 inch wand (with a 2 inch diameter head) pack a surprisingly powerful punch for clitoral stimulation, using a built in lithium-ion rechargeable battery that is about 80% as powerful as a plug-in version. This vibrator is also 100% waterproof and its made from medical grade silicone! We now make nearly every single one of our toys from medical grade silicone because it's simply the best, most comfortable and safest material on earth for sex toys. Our silicone is odorless and can be cleaned using soap and water or an inexpensive toy cleaner spray. Ladygasm is the American brand you can trust on Amazon. Email us anytime with questions!
