Liss America Professional Series 1 Quart Polished Stainless Steel Cream Whipper Bottle - Perfect for Barista Coffee, Whipped Cream, Desserts & Cocktail Mixing

I bought this product for my wife for Christmas.There are some real problems: The valve on my unit, controlling the discharge of the whipped cream doesn't seal properly; Liss USA doesn't seem to ever answer its telephone number; There doesn't seem to be any place where you can buy the optional decorating valve tips Clean-up on this unit requires very small bottle brushes--and tons of elbow grease.Buyer be aware . . .
