I'm just mega happy! Since I have quite a lot to do in fintess and bodybuilding area I really must say that this has been a long time again a shaker with which I am absolutely satisfied! Cleaning top! that's the best part! Moreover, even: the container can hold a whole lot ... so even large protionen! the bonus: the pill times! I usually separately but is really handy! and the mix is mega simple and good ... otherwise not leader would blender bottel certainly become the principle ... all are prallsiebshaker falls as simply back down! Those who like to clean a contaminated raw sieve? no one! just the stainless steel ball squeeze and Unters wasser..sauber ... done! and absolutely tight! I would buy again and again ... but already 3 piece ... =) so who has other Shaker can make by purchasing definitely nothing wrong!
