I am a prostate cancer survivor which has caused my ED. Tried pills and a pump to no avail. Investigated shots and an implant but I didn’t feel comfortable with the possible health risks. I came across the Erektor doing a web search for alternates. I would highly recommend sending for the free measurement kit. It fully explains how to get accurate measurements.I ordered my custom Erektor and received it in the mail a few days later. I eagerly tried it out that night and both my wife and I are extremely happy with this product . I highly recommend anyone suffering from ED purchase the Erektor I think you will be extremely happy with the results.
