Evidence: Body-safe Silicone; Reputable brand. How the score works: https://phareros.com/phareros-score/ ## Specifications - **Weight:** 1.32 lbs - **Material:** Silicone ## Description One button raises the suction, another lowers it, and a small LED display shows exactly where you are. That's the core idea behind the Rock Hard Auto from Pump Worx: a rechargeable, automatic vacuum pump that replaces hand-squeezing with simple push-button control. It also comes with two sleeves, so you can use it as a traditional pump or as a suction-assisted stroker. #### Key Features - **AutoVac Pressure System:** push-button controls let you increase or decrease suction gradually, with no manual pumping. - **LED PressureSync Display:** a visual readout of your current intensity level, so you always know where you stand. - **Quick Release button:** one press relieves the pressure right away. - **Clear cylinder with ruler markings:** both standard and metric measurements are printed on the cylinder. Total length is 11.8 in. (30.0 cm), with a penetrable length of 7.9 in. (20.0 cm) and a total width of 2.6 in. (6.6 cm). - **Two sleeves included:** an Elite Silicone comfort sleeve (2.6 in. / 6.5 cm wide) and a realistic TPE stroker sleeve (2.9 in. / 7.4 cm wide, 2.4 in. / 6.2 cm penetrable length). - **Rechargeable lithium-ion battery included:** about 90 minutes of run time from a 240-minute charge, using a pin plug/USB A charger. - **Materials:** ABS plastic, acrylic, TPE and silicone, in black and clear. The unit weighs 0.4 lb. (190 g). - **1-Year Limited Warranty.** The controls make this pump easy to use. Start at the lowest level and increase suction in small steps, watching the LED display as you go. Gradual changes feel better than a sudden jump, and the display gives you a reference point so you can find a level you like and return to it. If anything feels uncomfortable, press Quick Release right away. Keep sessions short, too. Pumps are best thought of as a way to add suction sensation to solo or partnered play. They are not a method for permanent size change, and overuse can cause bruising or injury. A strong vacuum calls for a little extra care, so let comfort set the pace. The two sleeves let you choose how a session feels. The silicone comfort sleeve gives the cylinder a soft, snug seal, which is what a traditional vacuum experience depends on. The TPE stroker sleeve suits a more textured, hands-on session with suction added. The two sleeves are different sizes, so you can find the fit that suits you. A water-based lubricant makes either one more comfortable and helps the seal. Silicone-based lubricants are better avoided with silicone and TPE parts, since they can affect the surface over time. Care is simple, but there is one thing to know first. This pump has an IPX0 rating, meaning it has no water protection, so don't submerge it or run the electronics under water. Wipe the cylinder and sleeves with a damp cloth and mild soap, then let everything dry fully before storing it. The sleeves are the parts that touch skin, so keep them clean and free of dust and lint. Charge the battery with the included charger when the run time starts to fade. Store the pump in a cool, dry place, away from direct sunlight. If you want vacuum pumping with steady, push-button control, the Pump Worx Rock Hard Auto is worth a look.
