Are you asking about the 3-Tube VED? If so, I have one that is battery powered and would recommend it.
The 3-Tube one is used by a lot of men with Peyronies Disease as there has been a 26 week protocol developed for use with it. It seems to bring length and girth back quicker than some other pumps.
