No more pumping needed with the Automatic Precision Pump - simply press a button to experience suction!
The Automatic Precision Pump works by sucking air out of the chamber, which causes blood to rush into your member. A soft rubber "donut" at base of the pump forms a tight seal during use. But the pump can work without the seal, too. To use the pump without the seal, press the "on" button with the one hand as you hold the tube firmly in place with the other hand. Some pump users also employ a penis ring after pumping to maintain the erection.
This sex toy is compatible with water-based lubes. It is not recommended to be used with silicone lubes. After use, carefully wash the sex toy with mild soap and water or try a sex toy cleaner for even quicker cleanup. Store this sex toy separately from other sex toys.
