I have a love hate relationship with this corkscrew. First of all, it is a great design, on those days when it works well. On those days when it doesn't I get VERY frustrated. The idea is that you twist the top of the corkscrew which turns the twirly part into the cork. At the same time, the arms of the unit go up in the air. You keep twisting until the arms have raised way up and then you push down the arms and you have the cork pulled from the bottle. Sometimes it does not work, however, and can break the corks, or not pull them out well. This is especially true with the plastic corks which are popular now as the industry begins to migrate toward screw tops. Ease of Use It depends on what bottle you are using this on as to how hard it is to use. Some bottles have it where the lip that fits over the top hits it perfectly. Everything gets in place and the cork comes out. However, sometimes that is not the case. The whole thing does not line up that well and the cork can still break off, or in some cases, the handle or corkscrew part itself (which has happened to me) Durability I have had quite a few of these corkscrews. I tend to reach for them as a last resort if I can not find anything else. I have had the corkscrew part break off, the handles, or the whole thing just malfunction. These might work well for a while and then break, or break pretty quickly. Design The design is a good idea, but has some flaws. With fine tuning, perhaps it would be much nicer to use. Despite it saying stainless steel, I have had some with that label break off too easily- not a characteristic of true stainless steel. If you hit the right bottle, it can work like a charm. If not, it can be a frustration. As the industry moves more toward screw tops, perhaps we might find that the corkscrew might become a thing of the past. Not always a pleasant thought for those who enjoy that familiar POP sound when opening wine that distinguishes it from other beverages.
