YEA im surprised to hear these amateur ways of removing sleeve from so-called professionals, that jp tool is second to none, i have NEVER tried anything else, as the ways mentioned can only do damage, the jp tool, you just pop it in, and pull it out, it has rubber that expands in a sense and grabs on, so when you remove your not PUSHING with a toothbrush on the bottom of a sleeve, wich happens to be the weak part, and im sure the stubborn ones, it HAS to make them slightly out of round. pm me i can direct you where to buy for under 20$...
