The shape of the shaker is ok and is also comfortable to hold. Too bad that you can not choose the color in advance, because not every woman when she gets picked this color at random, like pink. In the description of what is "red", but for me it was more of a dark pink. I now have a shaker for several days in use and am not very satisfied. From the capacity is sufficient slack off for a protein / protein shake. And to fit comfortably in my larger handbag on the go .. you shake not the same intensity and at least 20-30 seconds to prepared Shake, then quickly form clumps, which unfortunately will not go away by the very coarse sieve. Some lumps remain sometimes stick to the screen, which is not very appetizing. The silicone ring is removable, which makes cleaning underneath. However, this is only after some "fiddling" again almost frame suitable. My feeling I have the silicone ring again inserted correctly (according to the description: Silicone ring to remove upwards vaulted place over the mouthpiece; the ring used for rinsing the cover again so that the bulge of the silicon ring fits on the vault). However, could not the cover (without thinking about it) simply turn back, so me then something has leaked the first times ever in Shaken. Last bothers me personally yet, there is always something douse each of the shake when closing the mouthpiece the "snapping", which is not nice also. I now always had a handkerchief or paper towel drübergelegt before I closed the mouthpiece. I think that this Shaker is not long remain my companion ...
