Andropenis vs Andropeyronies

Hi guys, can anyone give advice or info on these devices please 🙏

Because I cannot fathom what on earth the difference is between these devices, or the Androgold?! They all just look a different colour!

Can someone explain what the difference is??

( without just telling me one us specifically for peyronies lol. As i said, cannot see any difference between the 3. I may be being stupid )
