I absolutely love that this vibrator feels thumpy or like knocking internally on top of the amazing vibrations. It is a good size anal plug. I would say it is a probably a medium sized butt plug. It is easy to insert and I love that the base is long to fit in between the booty crack better. The app was very easy to set up and the slight cone shape at the tip of the anal plug made insertion much easier. It is a little bit difficult to clean in the inside to get all creases, but thankfully you can move the little tongue thingy around to clean it. I tried it long distance on a night my partner couldn’t make it here and we both loved it. I used this analogy plug on top of a clit sucker and it paired perfectly to give me multiple shaking orgasms
