I picked this one up after having a bad experience and ultimately wasting my money by buying "the beaded stroke master." But I had no problems with this one, the stroker works great! The fit is perfect and the material (silicone) provides a great sensation when coupled with lube. The material is sturdy enough not to break but flexible enough to be comfortable. The only downside to the stroker is the cost. However, after wasting my money on a cheap sleeve I would definitely recommend forking out the extra money for this quality product.
