I had the shaker from the 30-day Turbo Diet package of Apotal and find it full of handy because it fits comfortably in your hand and is dense. Even though I'm a chap, I must indeed take NEN shapely Shaker ;-) Now I order another one for my sister, so that they do not mean always pilfered when she is with me and we drink together our slim diet shakes. But since I Layenberger Fit + Feelgood drink for several months and have really taken off, I must say that the Shaker fits Layenberger - both good quality, I recommend them happy.
