The Bathmate Hydromax X30 long insert is a longer length accessory with many benefits. This insert has been designed especially for the X30 to achieve a perfect fit. Once men have used their X30 hydrotherapy penis pump and have seen clear results, they often switch the shorter X30 insert for this longer version. This insert prevents the penis from getting caught in the gaiter once it has increased in length. Every Hydromax X30 includes a shorter insert that can be removed and replaced with this one. This insert measures 9 x 9 x 9 cm and is a perfect fit for the X30 penis pump.
