Hi there ive purchased the sizegenetics extender and the hexagonal pistons dont seem to submerge under the cylinders regardless of what size piston i use or whatever combination i use,i messaged support and they just said i was doing it wrong i sent videos and no reply, was just wondering is this normal for size genetics to do,ive purchased sizegenetics 3 times with all the same issue the hexagonal pistons don't submerge and the tension is therefore never increased, just wondering what the solution is here do i just go do another company?
