I really liked the shape of this toy. The measurements are completely proportional from tip to base and make for a snug fit and a great prep stretch. I would have really enjoyed this toy in a larger size however I find that with the slightly smaller size the vibrations are more pronounced. This plug is probably better suited for intermediate to advanced users but in no way is designed to exclude beginners. This toy can be worn under clothing without being seen! I know my husband and I took it for a test in a movie theater. It would also be great for travel, just remember to remove the batteries from the control.
