This should be called the Intelligent Cocktail shaker. Not because it knows all the martini recipes. But because it is the easiest, cleanest and least fussy shaker we have ever had the pleasure of using. Everything is built in - no more searching for the strainer. Everything seals perfectly tight but there is no struggle to open and pour or to cleanup. The secret is in the top which flips to close one way and open to pour the other way. You don't even need to hold the top while you shake and there won't be any spills or explosions when it is time to pour.

Constructed of 18/8 Stainless steel and double walled. Dishwasher safe. 5 year warranty from Metrokane. Simple instructions, but no recipes on the back of the box. Holds 24 oz (.7 litre) and is 8.5" tall x 3.5" dia (21cm x 9 cm dia)

Even at twice the price this would be a smart purchase.
