Although the cocktail shaker looks more like a designer Thermometers, but must not be behind the classic shakers "hide". The stainless steel container is double-walled, is very good in the hand and is suitable to shake in one operation by its volume also is 2 or 3 cocktails. The best thing about him, however, his closing system. The black plastic cover (lid is very sturdy and stable) is a 1/4 turn open / closed and sealed by a thick (apparently silicone) seal off. Yes, because that is the most important and here fail many cheap or designer Shaker. This cocktail shaker is absolutely tight !!!!! The integrated screen is functional, practical and sets the cocktail a nice foam on. When stainless steel container it is clear but this elaborate cover can be quickly and easily cleaned under running water. The only thing you have to note is that the cover (the side with the Siebausgießer) is only closed properly when you press to close a rich KLACK is heard. Granted but the Shaker is not cheap (!?!) For tight, it chops and caught nothing, with the good processing high-quality materials have been used, he is great with 700ml capacity and therefore in my opinion worth its price. So it's inexpensive.
