Query: The best lever model I've used

We own three lever-type corkscrews: a rabbit, a sharper image, and a screwpull. The screwpull is by far the best.The rabbit is a design disaster. It pinches your fingers, it doesn't work well on plastic corks, and the screw wears out fast. I'm amazed that people give positive reviews to it.The sharper image corkscrew simply doesn't work: the screw goes in easily, the screw comes out easily --- oops, where's the cork? Still in the bottle.The Screwpull is by far the best. I didn't give 5 stars because plastic corks sometimes get stuck on the screw and can't easily be removed. I'm not sure what the solution to plastic corks is.
