There are several drawbacks associated with the semi-rigid implants which can result in sub-optimal erections. Penises with rigid implants are
never soft, which makes it difficult to conceal. Since this device is not as flexible as an inflatable penile prosthesis, a larger opening on
the scrotum is required to place it. Finally, rigid prosthetics have the risk of extruding through the skin several years later, since they are
always hard and provide constant pressure on the penis. This device may be suitable for men who cannot manipulate the pump, either due to severe
arthritis, neurological disorder, or revisions where an infection has occurred.
