ACTIV Protein Shaker Bottle | Leak-Proof, BPA-Free, Shatter-Resistant | ActionRod Mixing Technology for Smooth Blends | Gym, Fitness & Sports Mixer Cup - Black -28oz

Bought many shaker cups and finally found the right one with this product. Importantly, I feel confident that it won’t leak on me. The Perfoma has a unique technology with a moveable rod. You don’t have to deal with a blender ball or removable screen which can drip and get messy. This cup is made well too, including the flip spout cover - plastic is not thin. The cap always screws on right the first time. I was fortunate to be able to buy this item. It now says it’s not shipped to my area anymore. Thanks! Seller also sent me prompt emails when I inquired how to remove the “rod.” I’d recommend this shaker. It’s my new favorite!

Hello, I've recently purchased the "PerfectShaker" to replace my other one simply because my other one was a 24oz which I thought it was about time to have a more compact shaker that was the about right size in every way.As advertised this shaker utilizes an integrated whisk mixer which is connected to the inner lid as a base and it is removable if the need for cleaning.now for the integrated whisk mixer did a very good job for even mixing thickest protein powders.For a first impression, you get what you pay for and this be a nice bang for your buck for a compact shaker.Pros:This shaker does have the measurements on the side whether your needs are (oz or mL)The measurements go to 12oz while the ml fills to 400 even though this measure to 12oz this shaker can fill to 16oz. This is more than enough for your needs.Cons: None to be reported at this time.Will continue to report and update this review as time goes by.

This thing makes the blender bottle look clumsy and outdated. Blends my protein shakes to perfection, whereas the blender bottle still leaves part of the powder unmixed. I am definitely in love with it, no leaks and easy to clean to boot!

I absolutely love this shaker. It's definitely leak proof and does a fabulous job mixing the most stubborn powder. I especially like that instead of a random ball that can easily get lost, it has a metal sphere permanently attached to part of the cup. It's also not as tall/large as other cups which is perfect for me.

I love this shaker cup!! It measures up to 12 ounces which is perfect for my thrive shakes which needs 8-10 ounces of milk to mix with!! And best of all the shaker "ball" is attached to a rod coming down from the lid so it never gets lost and u can take it apart for super easy cleaning!!! I love these so much I just ordered 2 more!!! I only wish they had more than 5 colors.... cuz I want 1 of every color!!!!

I ordered three of these shakers. I'm very very pleased with them. They are leak free, easy to clean and solidly constructed. The lid cover rotates all the way back away from the spout for ease of drinking. I gave two of them as gifts and their recipients like them as well.

No fault of the product but as soon as I used it, my cat came running into the room because it sounds just like when I pour out his kibble in a bowl. Something I hadn't considered. So I can't really use it unless I go outside. It's a choice between a hassle and torturing the cat.

This is the perfect size shaker! I found it to mix powders better than the ones with a ball and it's a lot more convenient to have the mixing thing connected. It's easy to clean too.

This shaker bottle is perfect in every way and performs a lot better than the shakers with metal balls. First, the size is 1/2 litre which is more than enough for most people's protein shakes or meal replacements. Second, the top opening seals tight and with ease. No need to push in extremely hard to ensure tight closure, unlike my BlenderBottle which spilled a number of times due to this problem. Most importantly, due to its metal rod design this shaker blends the protein perfectly with my almond, cashew or coconut milks, which are a bit tougher to blend with than regular milk. I also use Kaizen Whey Isolate protein a lot, due to its simple ingredients, natural sweetener and lower cost. However, Kaizen is not the easiest to blend and was a downright headache with the BlenderBottle, always leaving lots of disgusting clumps. This Performa Shaker blends my Kaizen in under 30 seconds of vigorous shaking and makes it as good and creamy as an electric blender. Best of all, the entire bottle, including the metal rod are a breeze to clean. I have finally found found the perfect shaker bottle. Full marks from me.

I’ve tried other shaker bottles in the past, but this thing is insane! It pulverizes whatever you put in there. I had a stubborn protein shake that would not blend no matter how much stirring I attempted. Some of the ball cups get clogged, but this thing whips that protein shake into a chocolate milk consistency with no lumps left behind anywhere. It’s also a snap to clean! The piston mechanism really does work better than anything else I’ve used, and its much easier to clean as well. Will be buying a second one for my wife. She keeps stealing mine every morning!

This is my second Shaker bottle. It is a perfect size for my protein shakes (Single Scoop). Very portable, easy to clean with a sponge, rinse and set to dry. It mixes my protein powered very easily within a few vigorous shakes.

Perfect little bottle. Mixes the protein powder neatly and cleans up really easily as well. Couldn’t be happier. It’s compact and just what I needed to carry around.

Got this shaker about a year ago and still shakes up the same very smooth protein shakes with no hint of scratching or fading of interior or colour/label. Slightly bigger than I thought beings it’s described as “MINI” but definitely more my size than the regular ones.
