I purchased this OXO shaker based on the current review in the Saveru 100 and because of many other great products I own from OXO. The product leaks like several other cocktail shakers I already own. I was trying to eliminate the leaking problem I already have so I'm returning it. Too bad because otherwise it's a nice looking product and I like the double-walled feature. I would also say the jiggered lid is not very useful for any serious measuring since its only 1 ounces to the top.
