35CM rubber vibrating Urethra sound

Has anyone tried one of these Urethra Sound rubber vibrators I see them on eBay also on amazon too from China. 35 cm long 3 diameters I think they be long enough to reach the prostate. I once had some great prostate stimulation from using a catheter moving it little in and out was way more then anything I felt from prostate anal massage.

Having lots of experience with Chinese built products I can assure you that it is never going in to any part of me, where failure for any reason and could be a problem.
