EXTRA STRONG Protein Shaker Bottle- MAXIGO Stainless Steel, makes it your Best pre/ workout shaker cup, BreakProof & AlwaysFresh| 5xEasy| THE Gift for All Sports Lovers| BONUS Whisk Blender Ball- 28oz

I believe we live in a day and age when people who workout care.....about themselves and the planet.My friends call me a minimalist, I say I buy what I need to avoid wasting the planet on predetermined garbage.So I do not want a plastic anything and in this case protein shaker. I also want something to last until I die.This will not last. The lid screws on weird. The people who say it leaks probably cross threaded ot which is easy to do. The top seats weird and will not last. The top of the cup where the seal sits is on the sharper side, so it will eventually leak. This part should be rounded or flat.Just another throw away....I’ll recycle it

I drink an Isagenix protein shake every morning. I use the plastic shaker from Isagenix. This bottle is 100%! The steel ball inside makes the shake smooth and creamy. Much better than the plastic one. The shake also stays colder for longer. There is also measurements on outside of the shaker so you know how much water you are adding. I also use this as a water bottle during the day. It is easy to clean, the top stay closed while I shake the shake and I throwing out my plastic shaker. I really like this product.

the seal does not seal well, seemingly at random and regardless of how much I tighten the lid it leaks / dribbles when you take a drink

I should have read the reviews before buying. very difficult to close, and the cap get very messy after each use. Protein powder gets struck in the cap and doesn't mix properly.

Strong cup, Only negative thing about it is the cap. It doesn't close properly unless your push forward the cap and press down hard. Don't recommend it to busy people who are constantly in a hurry. My shake spilled this morning thinking it was fully closed when it wasn't. Good cup for price, if you can handle the delay of closing it.

Great construction! The double blender aspect to this makes mixing a waaaay better endeavor than otherwise. Doesn't leak.Overall 10/10!

I ordered this stainless steel shaker bottle because the plastic ones I purchased kept breaking. This bottle works great and completely breaks up protein powder. The only reason I didn't give it five stars was because the cap is hard to clean and dry. Other wise I love the bottle.

Works like a charm. I drink protein shakes all the time and this tumbler does the trick at keeping them cold. Very sturdy and almost impossible to spill anything.
