BlenderBottle ProStak Shaker Bottle with Storage Compartment, 22 oz, Leakproof Lid, Wire Whisk Ball, BPA-Free, Cream/Black

I bought this for my son to use during his track meets. He drinks a carb filler while running between races and then immediately has a protein/creatine/collagen mix after his last race. This contraption allows him to keep the different powders organized, and the cup is easy to rinse out with water at meet. The rim is also wide enough to dump the powders into. Brilliant- wish I would have found this sooner!

My husband loves this blender because it works well and how he's able to stash his vitamins. I was skeptical from the reviews complaining about the lid so when I went in store to check out what cups were available and tested the opening and closing of the lid and it was a nice snap knowing it's secured when you are not drinking or tipping the cup there won't be spillage and when you open it is like a little pop because if we are being honest reading the reviews almost turned me away but I'm super glad I physically checked it out myself, the design is convenient and the color is bold and beautiful

The protein shake cup is nice. I was hoping it had capacity to hold 16 fluid ounces, but even though it is physically larger than my old cup, it still only holds about 12 fluid ounces. However I am happy with the cup!!

It's a beautiful yarn beautiful color a very useful blender cup for protein milkshakes. It's very convenient that it has a little pill container that screws onto to the bottom of your drink canister. Only flaw I can see is that you have to work extra hard to make sure the lid closed tightly so that you don't spray everything everywhere when it is shaken to mix the drink. If you do that, it's a great container.

I feel the designer really too their time with this water bottle. It hast the ball to mix and my favorite part is the extra storage compartment. Supper convenient and love how i can keep wet and dry separate until i'm ready to use

I received the item without any problems. The quality is good, however it was supposed to include two storage jars, and I only received one (the 150cc jar). The 100cc jar, which should have been inside the bottle, was missing. Would it be possible to have the missing jar sent to me? Thank you.

I love the product but they sent it without the blender piece that went in the bottle. I called they made it right and sent a new one and even let me keep the other bottle I love the product otherwise.

The spout lid cap doesn't snap correctly on the drinking spout, so I have to hold a finger over the cap so that I can shake the bottle without my shake spewing out everywhere. Also because of this, the contents are more likely to spill out into your bag or you might lose some of your shake before you can drink it. Not good for transporting. The bottle and lid also aren't easy to clean.

to be completely honest i am really not much of a fan of the bottom container i feel like i lost room for my shake and I really dont have much use for it. Kinda wish yall wouldn't have decided to switch my choice of shaker. but it is what it is i guess.

i like the bottle itself. The bottle is a good size, seems durable and I like the color and the bottom compartment design. however the flip top lid does not securely close every time. it snaps but it is very difficult to get it to snap. it continously pops back up until you get it to snap properly. not worth my time for a faulty design. returning
