JOYSHAKER Electric Protein Shaker Bottle - Smart Automatic Shaker Mixer with Rechargeable Electric USB for Easily Make a Variety of Drinks - Removable and Easy to Clean Protein Shaker Bottle

 Was going to order a 50$ cup but saw this one with my name on it and had to take my chances on a cheap cup.. that being said I’m sooo glad I did this cup is amazing for its price would’ve spent more on it. Not sure how anyone has a negative review when it’s a 20$ cup doing way more than it should definitely worth the buy

Pretty good product, I have been using it for my protein shakes. It works perfectly. It does not leave any residues, it mixes the powders pretty well. The cup is robust and well sealed. It is not strong like a blender but it gets the job done while doing protein shakes or any other powder-based product.

 It works great

It misses the powder protein very well and is easily clean. Mixes the powder protein very well as easily clean I bought two of them one for Work and one for my house

I love this thing. I mix shakes in it and it works great. If it had blades I would do fruit smoothies.

 Can't lie, I had high hopes for this product. Very disappointed that it left so much residue and clumpiness along sides that I still had to mix in with a spoon. What's the point of having a battery powdered mixer if you still need to mix it up afterwards? I'm still searching for an answer to that question....note to seller!!!! Please remove the word "best" from title because you couldn't be more inaccurate. I've seen others for the same price my friend purchased on here and never had this issue. Now I've wasted my money on something that doesn't live up to what it was intended todo. Back to handheld shakersI've posted a video. There was no peanut butter added to this though with models I've seen used by workout buddies, they've been able to add some I need with no issues. I don't even dare with this, motor is not strong enough.January 27th Update: after using this product for a little over a week I still consistently have to shake up remaining clumps left behind from my protein and superfood powders. I have noticed that it does a better job on dairy based powders, while vegan and superfood powders make the motor pointless.

Great product! Works well! Blends good & does it's job good.

I love this so much bought 3 more for Christmas gifts!
