Nambe products are synonymous with the highest quality in materials and design, which is why they are frequently given as wedding gifts. I was shocked to read that three out of six reviews of the Nambe Twist Cocktail Shaker were negative. Before I address the four gripes--too heavy, too hard to remove the top, it leaks, and it doesn't look as nice in reality as it does in the product shots--a bit about me: I collect cocktail shakers, there's no one fussier about quality than I am, and I like to think I have excellent taste in objets d'art, which is what the Nambe Twist shaker is.
As for the design, whether you like it or not is subjective, but if you like what you see in the photo, you will like what you receive, because it looks identical.
The shaker is indeed weighty--it is made of an aluminum alloy mined in New Mexico--but I'm not strong and have small hands and I've never had a problem shaking and pouring from it. Neither has my girlfriend, who is 5'4" tall and has even smaller hands. To me, the weight, the solidity, of this beautiful shaker is wonderfully tactile and part of the reason this shaker has a high price.
As for leaking, this is the only shaker I've seen that comes with a thin rubber gasket around the rim for a tight seal that doesn't leak--at least mine never has. All my other cocktail shakers leak, including a Faberge crystal shaker that cost twice as much as the Nambe. The reason they leak is because there is no way to get a leak-proof seal without the gasket. Waterproof flashlights and other outdoor equipment work on the same principle.
The tops of virtually all cocktail shakers are difficult to remove after shaking because you have metal jammed against metal or glass to create as tight a seal as is possible without a rubber gasket. The Nambe shaker top is actually easier to remove than most because the gasket has just enough give to work the top off. But you do have to work it slightly. I have never had trouble removing the top quickly and easily. Many of the tops of my other shakers are extremely difficult to pry off.
You can buy a perfectly usable cocktail shaker for $10. When you exceed the $100 price point, you ought to know what you are buying. It sounds like some reviewers of this beautiful shaker didn't. Nambe objects are heavy. Even their martini glasses are heavy. Most people like the weighty feel of a Nambe glass, bowl, vase, or shaker. But it's no secret that weightiness is a distinguishing characteristic of Nambe products.
The reason for the weightiness is the aluminum alloy used in many Nambe products. This metal scratches easily but retains a high-gloss shine that retains its beauty even with wear. The metal is extremely conductive of heat and cold. If you stick the shaker in the freezer for 10 minutes, it will turn ice cold. The virtue of this is that when you fill the shaker with ice and liquid and shake, very little of the ice melts into the drink, so it isn't diluted with water, yet it is truly ice cold, far colder than any other cocktail shaker can achieve. It makes drinking more enjoyable.
The Nambe Twist Cocktail Shaker is the most aesthetically pleasing, tactile, functional cocktail shaker currently available. It's the only one I've seen that doesn't leak because the rubber gasket creates a leak-proof seal. The shaker is indeed weighty, but the design is easy to grip, even for a woman of small stature. After shaking, the top does take a second or two to work off--but that is true of nearly all cocktail shakers--and the Nambe shaker top is easier to remove than most.
The Nambe name is synonymous with superb designs, workmanship, and quality materials. If you like the look of this shaker, and you have the dough and the inclination, buy it. You won't be disappointed.
