Of course you can use it without a penis pump, but for men with ED that require extra vacuum suction to become erect, this is the best ring to help keep the fluids in the erection and make it stay erect for longer. Hollow rubber band with beads fits very snugly and is highly effective.
The rubber tubing does stretch slightly as you roll it down the shaft in order to fit any erection size. Add a couple drops of lube to the ring before rolling it on to reduce friction with your skin. The biggest bead at the top should be placed on the top pressing against the dorsal vein which is a physical boost to keeping the erection.
