this thing is incredible! it goes in comfortably. coming back out requires a little effort but is an awesome feeling. the taper below the widest point makes it a lot easier than other plugs I have. it seems like it is going to be easy to get used to wearing for extended periods of time. it stays in really well. the one I received measures 2.85″ in diameter at the widest point and an overall length of 5.6″ with 4.8″ of it insert able. it only took me about 5 minutes of getting used to the diameter and before I knew it I was popping that box. it’s awesome!
