This is an amazing product. I did a lot of research and eventually decided to purchase this model, out of all the top brands and models. Although they were sold out in a couple stores and were not available online, I went out of my way to get it, and It was well worth it. It was the perfect fit. The premium silicone is a dream. It really does retain body heat and is very easy to clean. The charging doc is genius. I insisted on the dual motors, and was happily surprised by how much I liked the independent rotation, having never tried any toys before with that function. The whole darn thing is also fully submersible! I can tell this one will last me for years, and as if I was worried about it, it has a year warranty to boot. LOVE IT.
