I have to admit that when I opened my box and saw this toy, my eyes got wide! This toy is 7 inches long, and 1 3/4 inches in diameter. It is made of X5, which is a realistic feeling material. As I read the back of the package, and read that X5 has memory, I really wondered what that meant. So, I took this very nice cock out of the package, and it really has a realistic feel! Then I found a hole in the top, and that really made my eyes wide! As I checked this out, I realized that this is a sleeve over a sleek silver vibrator. It is also waterproof, which is always a plus. I washed this big boy in antibacterial soap and water, patting dry after. Always remember to use only water-based lube with this toy, as it is a silicone toy. After use and washing, a light coat of talc or cornstarch will help it retain the soft texture. TooTimid also sells CyberSkin Renew, which is nice to have. Two AA batteries, and it was ready to go! This is really easy to use--a little twist of the knob at the bottom. I found the vibrations to go from low to high, and everywhere in between. With a little clit stimulation, it provided an outstanding orgasm. I'm a believer in this memory penis!! http://www.tootimid.com/The-X5-7-Vibrating-Dildo_p_2618.html
