Ultimate Stainless Steel Electric Shaker Bottle Vortex Mixer, USB Rechargeable, BPA-free & Leak-proof Protein Powder, Cocktail Blender - 1 Bottle

Product is awesome! My 17yr old loves it and uses it after a workout to mix his protein shakes! Stopped working and company sent out a new one after 8 months of using it! Amazing customer service!

It's a nice shaker, hopefully the one everyone else gets doesn't end up malfunctioning like mine did. The button that starts the blender mechanism sticks and either you have to hold it in or the blending doesn't stop when you press it to turn off. It's a nice container just needs a few fixes.

The product was damaged in the box. The product was not what I expected it to be it didn't work in the manner that I thought it would work or the manner it was described.

The product overall is awesome. Does exactly what it's supposed to do. Mixes all of my supplements well without any hesitation from the motor. My only issue was when the product arrived it appeared to wet inside the cup so it had a rancid like smell. I dont believe it was used but the smell was pretty bad. After I washed it with soapy warm water the smell went away. Other than that the product is awesome.

Very little power. After I added the needed scoops of powder, it was spinning so slowly that it was unable to mix.It may work fine if you only need to add a little powder, flavor, tea, etc.

I absolutely love this blender. I use it to make a protein coffee drink in the morning. So far, it has not failed me. The design is perfect for the busy person on the go that likes to make protein drinks, shakes, smoothies, etc. You definitely will not regret this purchase. Fair warning, it works just like every other blender. Make sure you put the lid on securely, or you will be wearing it. Thanks for such a great product!

I have a Blender Bottle and like how it performs, but saw this and thought I'd give it a try. The first time I used it I filled it with water to the max line indicated on the side, and, per the instructions turned it on. A few minutes later, after cleaning up the flood of water it flung out everywhere, I reduced the amount of water and tried again. You're instructed to turn it on and then pour your powder into the swirling vortex. I did as instructed and let it mix for about 20 seconds. As I drank the shake, I noticed powder gathering at the bottom of the glass, so I powered it up for more mixing. But, at the end of the drink, I got a mouthful of powder anyway. I don't get unmixed powder in my Blender Bottle, but it may be because I can add more water to that. If this was offered in a larger size, it might work better, and it will probably work for other drink mixing uses, but for now it falls short for my needs.

I am expecting a huge size of bottle because of the description but it's so small and the power is not that great, I contacted amazon and told me can't return because I've use it then how would I know if the product that I purchase is working or not if not going to use it????, I am very disappointed.
