Bathmate penis pump for erect length

Make sure the erection length of your penis is not more than 5 inches for Hydromax5 and HydroXtreme5 and 3 inches for Hydromax3 and HydroXtreme3. Choosing a Bathmate penis pump that is too small will reduce the growth space and even hurt when used. See the guide to measuring correct penile erection here.
