The Little Chroma might look like any typical vibrator, but trust us when we tell you that this is a clever and very unique toy. Made out of metal, this toy is easy to clean and is safe for just about everyone to use. It also holds temperature well so you can heat it up or cool it down. The Little Chroma is also waterproof, and it stays waterproof up to depths about 10 times deeper than your bathtub which we think is absolutely fantastic. The vibrations are quite powerful, yet surprisingly remain very quiet which is excellent for people who do not want the neighbors knowing about their sexcapades. The one thing that truly excites us about this toy, tho, is that it can last you a lifetime. How is that possible? Because the folks at Jimmyjane have designed and patented the world's one and only replaceable motor for vibrators. The motor is the same size as a standard AA battery. The Little Chroma is powered by a single AA battery, which is included! (Vibrator)
