Original Shaker Bottle - Battery-powered for Smooth Protein Shakes - BPA Free, 20oz Cup (White)

The product is SUPER easy to use, the only thing I wish they’d included was how to insert the batteries. Took me ten minutes to figure out the rubber bottom will separate from the motor by simply pulling it off. Nowhere in the instructions did I find this, maybe I just didn’t look well enough. Either way, the bottle works perfectly for my purposes, which is to get psyllium fiber to mix enough with water that I can drink it quickly. Same goes for the gelatin and magnesium supplements I use.

I got this because I was tired of that stuff that stays at the top of my shakes (protein). I was skeptical about it, but listen.... It works. Depending on how much powder you put into it, it can make the mixer slower but it still works. It's not a large cup so you wont be able to fit the 3 gigantic scoops recommended on the big bag. What it does fit (i use one giant scoop which fills about 1/3rd of the cup), it mixes very well. I don't only use it for shakes, I use it for tea, instant coffee (cold) and pretty much everything. It's my go to cup now. It's battery powered and I used amazon rechargeable batteries. It's very easy to clean. Fill it up with water and soap and turn it on for a minute and it does a pretty good job. There's not a lot else to say about this cup. It does a great job at mixing it completely. Way better than my spoon did and it makes my shakes so much easier to drink. I no longer have to chug down chunks. That's exactly what I was looking for.

I start each day drinking creatine and collagen powder. Since both are difficult to fully mix and settle to the bottom of the glass, I'm pleased with the shaker; it allows me to continually mix the powders as I drink which means I waste less of the supplements. I look forward to taking this when traveling since it works with two AA batteries and its size is packable. It's not as robust as an electric mixer, but because it's so easy to use and clean, I now drink my morning supplements routinely without thinking about the hassle of having to clean up after.

The motor started moving very slowly... not enough to mix anything. It worked well for 9 months. As I was writing this review, I noticed that it had a one year warranty. Contacted the seller and they are honoring the warranty. Kudos I bought another brand to replace this one (before I knew they would honor their warranty.) It was more expensive, but not as good as this one was. Good product and good company.

I bought this forever ago and I used it a few times but I forgot to clean it out and I don’t think I’ve touched it since. It’s probably all disgusting now to the point I might throw it away but I honestly forgot I had it. As for the product, it works fine, I’d imagine the spinner isn’t too powerful so don’t throw in a bunch of solid stuff expecting it to blend but it does what it says it will.

I have bought this same product in the past and it was great! THIS ONE?!?! UTTER GARBAGE! Out of the box, it barely turns (with brand new high quality batteries). The gasket was even the wrong damn size, so when I tried to just shake it, it leaked everywhere! How did this piece of trash pass quality control?!

I followed the instructions of adding water first, starting the motor, then slowly pouring the mix in, and even after minutes of mixing there are too many clumps. I've tried it with different levels of water, for different durations, setting the bottle perfectly straight up as well as with a little bit of a tilt and always with only one scoop of mix and the shaker simply doesn't do the job. I believe the flaw is in the nature of the product and not specific to this product. To expect to get close to the same power of a blender connected to an outlet is a little optimistic.

Mixes protein well, easy to use, easy to clean, worth the price. Very Durable, still good after over a year.
