PromixxPURSUIT Protein Shaker Bottle – Premium Sports Shaker Bottles for Protein Mixes and Supplement Shakes – Easy Clean, Durable Protein Shaker Cup

This is a great ingenuitive product. I always use the old cups that had the spring ball inside it, and it never fully mixed the protein powder in the water. Using this shaker bottle, I've never had clumps of protein at the bottom and it's always thoroughly mixed. The bottle is easy to take apart and clean in the dishwasher, but I suggest hand cleaning it with dish soap after every use. The bottle itself is really durable. I don't know how many times I've dropped this on a hard floor and it's never even had a scratch on it. I noticed it to be leak proof and I really feel that it's a great value for the money. Think of it this way, this bottle only costs about $1.50 more than the inefficient Shaker bottles with the metal spring ball. Well worth the price for the for a genius solution to the protein shake problem.

I drink a protein shake/smoothie everyday for breakfast so I bought several of these bottles to replace my old worn out ones. They are nice looking, great quality and work great. Only one leaked, only because the rubber seal in the cap came undone. I pressed it back in place and it seals fine again. Dishwasher safe on top shelf.

I was a little leery of the strainer being enough to mix everything, but I hate having the rattly ball or wire thing to listen to and mess with trying to clean inside of a cup. So I gave this a shot.First impression, it's sturdy, I dropped it on a tile floor (by accident while unboxing it), no chips, no cracks, not even a scuff. I'm not the most graceful person, so the drop test was a nice surprise and a big points up.The next thing I noticed was everything was easy to get to for cleaning, no finger pinching wire cages, no special little brushes I would immediately lose required to clean any part of it. Even the strainer part is easy to pop on and off so you can just wash inside and out no trouble! I may need to use a toothpick if I need to get the gasket out, but those are common and easy to find.Speaking of... There is a gasket for the lid, NO LEAKING! A huge deal if you are going to be tossing this in your bag full of your drink or with a few drops left. Either way, you don't want to find out it leaks! The little drinking cap seals nicely too.And though this seems an afterthought, and it really is the point of this cup, the shaker/strainer does a really good job of mixing in powders. I've been using this a few days now and even made the mistake of getting distracted right after pouring in the powder so it sat on the liquid for several minutes. It formed that big old dreaded clot of powder and this broke it up and mixed it in perfectly.I couldn't be happier!

It’s a great mixer without the annoying ball and was great for a few months but started leaking

This shaker has held up to my expectations so far. There is no rattle due to the integrated mixer on the lid which was the most attractive feature of this shaker for me and comes in an array of neutral colors. Its easy to clean by hand, and durable (I've dropped it a few times already by accident...) It also has measurement markers on the side of the bottle so I dont have to dirty up my other measuring cups. My shakes never turn out clumpy and for $10, its great value for the quality of this product. If it somehow breaks, it wouldn't even bother me to order a replacement since they are only $10.

Great shaker bottle. Love that it doesn't have the metal ball rattling around when your bottle is empty.It's a fact of life, we are all mostly drinking out of plastic bottles in some direct or indirect form. There are micro plastics making their way into our body systems and its really hard to avoid them. This bottle limits the exposure in a sense since the metal spring ball inside other shaker bottles isn't bouncing around violently and loosening up micro plastics from within their bottles. This design possibly gives us a small victory in the grand scheme of things.BTW Promixx offers a metal insulated bottle, but it leaked badly so I had to return. This on the other hand has been performing like new for years (I own a bunch). No leaks.Also be cognizant of how much water you put in this bottle. Too much water and you won't have the room for the water to create force to adequately mix your dry powder well.

Simply amazing. I have had quite a few shaker bottles but this is the best one. Zero clumps at all in my shakes. Easy to clean and so functional. I was skeptical at first but this product should be #1. All my protein shakes come out super smooth.

I'd give it 3.5 stars. Lasted about 2 years before the rubbed stopper on the lid came off and would no longer stay on when opening the bottle. Then it started leaking around the edges of the lid shortly after.But for the price, 2 years isn't bad I guess.
