Tried all 5 of the tenga 3D series, this spinner is a welcome experience. Definitely not the same as the 3D. The texture is harder and it feels firmer to grip after inserting yourself in it, so you cant really vary the grip strength on your shaft unlike the 3D series. However the spinning gimmick when you rub it up and down on yourself is fantastic, sudden climax, will get you to the top of the world in no time. Not for edging or strength training.
In the end i still prefer the Tenga 3D zen, have yet to find anything that can beat this.
