Well, a lot, surprisingly.
I just made my first martini so take my review with a grain of Lemon Twist.
First thing that went wrong: while shaking the ice and cocktail mix, the thing froze on the outside, bad enough that the ice stuck to my fingers. Why not make the exterior from some rubberized material?
And way worse: the cap stuck. When I attempted to pull the cap off, only its metal shell came off, and the plastic cap remained stuck. No amount of manual twisting (bare-handed, or with a towel) was enough to remove the cap, until I donned a rubber glove for better grip. This is not exactly acceptable - why not make a screw-in cap, like most bottle caps?

I'll return this to BevMo (which BTW sells it for double the price on Amazon).

Easy and fast to use. Well constructed.
As with all Riedel glasses, these are great quality and nice to use.I wish they were a tad larger, but other than that, they are perfect.
I used this at a party recently and was in awe... just put it on the bottle, spin, and off flies the top! It feels great in your hand, and looks gorgeous wherever it lands on the table... unlike other foil cutters available.Also - it's very difficult to cut yourself with this thing, and it's also tough to break. I notice it's not available on amazon right now - but I saw it at Williams Sonoma, so you can look there if amazon doesn't have it.
Now, i love the idea of having a chrome tub caddy until 2 months into having it, it begain to rust. Then the candle holder & the wine glass holder rusted off !!! I am now on the looking out for a plastic covered tub caddy. A caddy is awesome to have but not in chrome !!!
Received my Corkpops opener as a gift three years ago & have been amazed at the ease of opening a bottle of wine ever since.I always order two boxes of Corkpops refills so I never run out of cartridges.Love it!!!!
I am wine collector w a sommeliers diploma - so I've done a lot of tastings over the past 20 years. Obviously the top league is held by Riedel - the old guy did his research on glass shapes (although debatable whether optimal for every varietal).
