I had a few of these pill crushers or pulverizers, but they didn't work well for me either by not crushing pills fully, clogging my peg tube, the plastic cracking under stress or not having the hand strength to properly use it. What I did wind up using instead was an electric coffee grinder, purchased and solely used for pills, which worked well pulverizing them into a powder, which I then mixed into water and through the peg tube without clogging.
Good luck!
