I just got my [words=https://officialhydromaxpump.com/?uid=6&oid=2&affid=98 ]Bathmate[/words] today, and i tried it out, pretty awesome. i used it, but as i stopped pumping, there was a tiny air leak in the end of the valve where little bubbles of air were seeping in. at around 11 or 12 minutes in the workout, the [words=https://officialhydromaxpump.com/?uid=6&oid=2&affid=98 ]Bathmate[/words] was about 1/2 full of air. is this normal? or is it a defective product?
