That is the same device as the Jes-extender. Same goes for; Penis master, Peni master, maxstretch and what ever they are called. There are lots of them out on the marked but they are all copies of the Jes or simply re-sellers of the Jes-company. You do not want those. Take it from a guy that have been there and done that.
If you are going to buy a extender I recommend that you get the vac-extender 2 from
www.autoextender.com .
