Why would you spend close to $30 for a shaker?
You can buy a shaker from walmart for about $2.99. 
Can't speak for him, but for me, when it comes to water Bottles, Umoro brings a simple concept into a new era of elegance and sophistication. With BPA free, clarity-retaining shatterproof plastic and a custom made storage lid and quick release shaker, this is the fitness accessory for all health minded individuals! I can rapidly go from bottle to protein or pre-workout shaker at the press of a button!
I also can concentrate better on my workouts due to its TRUE LEAKPROOF PROTECTION - they've incorportated rubberized seals to offer truly revolutionary 100% leak-proof prevention. That, paired with laser precision twist groves, offers an unmatched fit you won't find anywhere else. It even comes with a convenient carrying strap, bringing "grab-and-go" to a whole new level.
In addition, it's GUARANTEED - I love this water bottle and shaker combo, and I know without a doubt that you will too, SF1900. However, if you need anything, they're there to make things right. For a full year from your date of purchase, you are completely covered under our factory warranty from cracks and leaks!
I think it's worth spending so much money. Could be the difference between getting huge and not getting huge.
