Penis pump and extender combination. Need opinion.

Has anyone tried the above combination, targeting mainly length?

I have limited time for manual exercise or perhaps just has exhausted all possible gains from it. Currently decided mainly to target length before aiming for girth. Thinking to use penis pump first in the morning. The extra post pump engorgement will enable me to fit into the largest (blue) sluice of Penimaster Pro. Hence I should spend more time stretching, ideally speaking.

Otherwise, being uncircumcised, my frenulum seems to take a lot of beating from this as both involves glans expansion and subsequently stasis of blood in the frenulum. Noted it’s turning black gradually and sometimes painfully, with the need to immediately cut down my extending session.

Let me know if anyone has tried this combination to target length, especially if you’re uncircumcised.
