I myself am happy with the waiter's friend type, but my wife prefers the wing type (with two opposite geared levers). In our experience, these last only a short time before breaking or becoming misaligned. She received an OXO brand this past Christmas, which looks pretty sturdy but it does have a non-steel "worm" so I wonder if there will be problems.
Is there a reliable brand available of this type corkscrew? Thanks.
