I purchased a [words=https://officialhydromaxpump.com/?uid=6&oid=2&affid=98 ]Hydromax[/words] last Thursday and had it by yesterday (Monday) -- so big kudos to [words=https://officialhydromaxpump.com/?uid=6&oid=2&affid=98 ]Bathmate[/words] on the speedy shipping. Unfortunately, I found that the valve latch was very difficult to move and wouldn't stick at all if moved to the left position. Addititionally, as soon as I started pumping it, air bubbles started leaking in from the valve causing it to lose pressure. I tried the "place it on a flat surface and pump it" advice from the web site, but that didn't do anything. I have emailed customer service and will update you on the response.
