I thought the LG hanger sleeves were awesome at first but they lose their stiffness about as fast as the regular
phallosan ones from my experience and they're just as expensive. I may be using them more than most though. I usually clock 6-8 hours at medium intensity every day but I shouldn't be negatively affected by that. I should be able to use it as much as I want. That's kind of the whole point of it.
I thought about trying some cheap ones but I can't help but feel like they would suck, not just because they're cheap but also because they're so stretchy. I actually prefer my sleeves to be dense and stiff as fuck so there's absolutely no loss of suction even at higher intensities for long periods of time.
But if you think they work good I might try them though.
