BlackubeProtein Shaker - BPA Free,Tritan, 600ml 20 oz, Portable Electric Shaker Bottle, Rechargeable, Electric Blender, Suitable for Fitness People, Self Stirring Mug,Waterproof (Black)

I drink protein shakes as part of my diet. I originally thought that I needed a portable blender, but I tried several and none of them served my purpose. This shaker fits my needs perfectly. On the downside, it does not work with ice or anything heavy or course that needs to be blended. But it does a great job of stirring up my drinks. NOTE: When I first used the shaker, I was afraid that it was not powerful enough to mix up my drinks. But I found that if I put the water or milk in first, then started the stirrer, then added the powder, that it mixed the drink with ease.I find that my protein drinks often start to separate within seconds of mixing them. Being able to push a button and have them remixed just before I take a drink works great. If you want to go cheap (and there's nothing wrong with that) you can get a mixer that has a steel ball in it and just shake the drink up. I found that to be noisy and inconvenient.I was worried that the mixer would be overly noisy or distracting since lights spin around while it's mixing. But I found it to be fairly quiet and the lights are not overly intrusive.A minor nitpick is that the measurement on the side of the mixer is 6, 10, 14, 18, and 22 ounces which is slightly annoying since I always want to measure in 4, 8, 12, or 16 increments. Oh well, not that big a deal.I really like the lid. I had some blenders that were really hard to open. With this one, you push a button and the top flies open making it easy to access the contents. Also very easy to close and keep watertight.Sadly, I cannot really speak to how long the mixer stays charged. I use it until I'm done and then re-charge it every night, so I don't know how long a charge lasts. Long enough for me, but -- again -- I don't know how long that is.On the whole, I found it to perfectly fit my needs and I highly recommend it.

I have been using this regularly for few months and I would like to say I am so satisfied with the purchase how there are some pros and cons I would like to mention and I hope the seller could update themPros1. This infuser mixes powder well2. Very convenient3. Love the lock on the button ( which I only figured it out yesterday and that holds it all together and it doesn’t leak at allCos/Positive Criticism1. I really hope if they can have a compartment underneath to keep the protein powder or supplements seperate, even a little box on the side would do2. Hand washing can be a pain as I’m a big fellow with big hands often struggles to get my hand in there3. If the blade can be taken out with a click would be easy yo cleanEither way I would still give this product a 10 star rating as I am loving it.Highly recommend and go for it people and don’t forget there is a lock in the button.Thanks guys for a great product.

Worth it! Amazing quality and perfect lookMix powder very well with ice cubes tooAnd spinning lights are so coolPowerful motor and battery life is good

Definitely no leaks and is good value of money but I brought this shaker for my Huel powder and it's not good enoughI use 2 scups of powder and shaker can't handle it

Works as advertised! I have used either water or milk with my protein drinks. Always remember to add the protein powder after the liquid. Secure the lid properly, press the speed selector twice on the attached battery and the drink is ready. Cleaning is just as easy with hot water only and pressing the selector twice. Now remove the battery, empty and rinse the cup and you are able to use any soap to clean your cup.after this is complete.
