Consistency is key. I started out with the x30, but quickly outgrew it because my girth is 6.7”. My length is right at 7. So the next best option was the wideboy, which I love. Been using it and make an effort to pump every day in the shower for the recommended 15 minutes, Jelqing in between sets. Girth is always the fastest results to show, for me at least.
I’ve consistently measuring at 7x7 out of the pump, or if I pump for a little longer can get to 7.5 girth. Length is much slower progression, but keeping it up over the last year, year and a half. Using a cock ring at the end to hold the gains is a good option to consider as well after pumping.
