TOPIC: Phalosan sleeve alternate?

I just got the phalosan few days ago, and ripped 3 sleeves so far due to trying to get it over the suction cup. I was wondering if theirs alternate sleeve I can buy that is stronger and preferably cheaper. I don’t want to phalosan to go to waste. I believe it has potential but damn sleeve ripping

Seems to be a pretty common occurrence, from what I know. I think the company sells sleeves: email them. Most people I chat with get different devices eventually.
