Designed to help enhance erection, improve endurance and feel amazing all at once, the Optimum Series Automatic Smart Pump by CalExotics increases endurance, improves stamina and amplifies your member with three unique enhancement exercise modes. Strategically crystal clear so you (and a partner, if desired) can watch your progress, the Smart's long chamber is naturally magnifying. Over its entrance, a plushy, super-soft donut cushions skin like magic as it maintains a great seal. Past that, a clear textured sleeve fastened to the interior snugly surrounds the shaft. At the touch of a button, the first of the three unique pre-programmed suction exercise modes begins. Created to help build up endurance in the face of stimulation while also firming the penis, the first one sucks for 4 seconds with a slow release. The second sucks for 5 seconds, holds pressure for a full minute and repeats, and the last sucks for 8 seconds and holds pressure for four minutes. A dedicated power button and separate quick release make control a breeze. Recharge this premium pump in 90 minutes with the provided USB charging cable to enjoy 60 minutes of high-speed stimulation or 80 minutes of low speed suction. To track progress, use the incremental measurement marks on the cylinder shaft. The premium sleeve fits into most standard pumps, but can be used independently for a passionate stroking experience. Enjoy easy clean-up with this maintenance-free stimulator sleeve; simply wash with warm soapy water or your favorite toy clean. Compatible with any chosen water based lubricant. * The Automatic Smart Pump Measures approximately 12.75" (32.4cm) in total with 9" (23) penetrable. It's approximately 2.5" (6.47cm) in diameter
