I had to use the needle nose plier trick a couple times, but I think I figured out the problem. When you hold the bottom button to remove the cork, be sure to hold it until it stops automatically, even if the cork is clear of the bottle. This will pull the cork fully up into the reciever where there are plastic ribs that keep the cork from spinning when you press the top part od the buttom to eject the cork. This opener easily pulls even the most stubborn plastic corks; LOVE IT!
Use needle nose pliers...it works. I've had to do this once with another brand electric opener. Reach needle nose pliers into the opener; grab the cork or what's left of it and hod while while depressing the top auto eject portion of the button.
