Neal, I use the Champ-Eazy prongs from time to time. Handling is not that easy, but it works. The inconvenient is the very loud pop which is not state of the art in the restaurant or sommelier business. But it's a perfect tool for banquet type of events when you have to open a larger number of bottles.
JFTMOR: FF1.x worked just fine, so there was no need to update, until I went to a site that required FF2: The Austrian Academy of Science has put Karl Kraus's "Die Fackel" online a wekk ago. The site needs FF2, that's why I updated.
