Some sessions are forgettable. This one will not be. The Optimum Power Ultimate Power Stroker is built to give you something genuinely different, a stroker that combines vibration, pulsation, and escalating patterns with a four-row bead channel that physically works you from base to tip. That combination hits differently than anything passive.You get seven independent vibration and pulse functions to work through, so you find what actually does it for you instead of settling for one setting and calling it good. The four rows of stroking beads run at three independent speeds, which means the sensation builds and changes in ways your hand simply cannot replicate. The sleeve itself is stretchy, textured, and removable, so cleanup is quick and storage is clean with the snap-on lid. It runs on four AA batteries, which means no waiting for a charge and no dead device when you want to use it.This is a well-thought-out stroker from a brand that has been making this category for a long time. If you have been making do with something basic, upgrading to something purpose-built for real sensation is one of those decisions that pays off immediately. Add it, try it once, and you will understand why men who take solo time seriously stop settling.Product DetailsSleeve Length: 5 inches (12.75 cm)Sleeve Width: 3.5 inches (9 cm)Overall Length: 8.5 inches (21.5 cm)Overall Width: 3.5 inches (9 cm)Vibration Functions: 7 independent functions of vibration, pulsation, and escalationStroking Speeds: 3 speeds of independent stroking actionStroking Beads: 4 rows of extreme stroking beadsPower: Requires 4 AA batteries (not included)Sleeve: Textured, super stretchy, removableStorage: Snap-on storage lid included
