Which traction device for bigger glans?

[axolotl]

Hi,
I recently bougth a Penimaster pro, but unable to put on because the valve doesn't seem to close right and also my glans' width is ~5cm but the plastic ring hole's diameter is ~3 cm so probably it is too small for me, probably I have to send back.

I read that the restorex clipping machanism also causes issues on the glans, so if it causes pain for average people then I would get even more, I think.

Does anyone know about how the Andropeyronie or Phallosan forte would fit? On the webpage I see that the second one has glans chamber sizes S, M, L.

Thanks in advance
