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

I love this cup, I love that the plastic is very thick and durable, I love the price of this cup, and I absolutely love the storage, and I love how interchangeable the storage containers are because the lids of the storage containers are what click into the cup so you could just take your pills or one container with you and don't have to have the whole stack, I really love this cup

I recently purchased the Blender Bottle ProStak and I'm impressed with the design and features. The built-in storage compartment is a great idea for carrying protein powder or supplements, and the leak proof lid feels secure. The included wire whisk ball should make mixing shakes easy, and the bottle feels sturdy and well-made. The 22 oz size is perfect for protein shakes and post-workout drinks. Based on my first impressions, this looks like a convenient and high-quality shaker bottle for anyone with an active lifestyle.

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 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.

It is only marginally better than stirring with a fork. It had some features at the bottom, a container for the powder and one for pills, which i would not need or use. After shaking vigorously it was extremely frothy and i still had to use a sieve to remove clumps.

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.
