Need suggestions for reliable air pump ?

[tiritera]

I should have mentioned that the 45 minute session should be at 4 hg or lower.

When pulse pumping slowly increase the vacuum to 5 hg and leave it there for three minutes and then reduce to 2 hg for thirty seconds before returning to 5 hg for another three minutes and repeat the process for 20 minutes or so.

Is this one with Smart mode? https://www.kodidistributing.com/pr...-penis-pump-kit-8-or-9-inch-cylinder-tpr-seal
