PromixxPursuit Shaker Bottle Insulated Stainless Steel Water Bottle and shaker Cup, 18oz, Ocean Calm Blue

The Promixx Pursuit Insulated Stainless Steel Shaker Bottle quickly became my favorite after just a few uses. The build quality is excellent — the stainless steel feels solid and durable, and the insulation actually works. My shakes and water stay cold for hours, even when I leave the bottle in a hot car or bring it to the gym. Fits great in all cup holders.The lid design is one of the best features. It seals tightly with no leaking at all, even when I toss it in my gym bag. The flip cap is secure but easy to open one-handed, and the wide mouth makes it easy to add protein powder without spilling. Cleaning is also simple — no weird corners where powder or residue can get stuck.The shaker insert inside blends powders smoothly without needing an extra ball, and it doesn’t rattle around while you’re drinking.I’ve tried a lot of shaker bottles over the years, and this one is by far the best combination of insulation, durability, and no-leak performance. Highly recommend if you’re looking for something a step above the usual plastic options.

Love this shaker bottle! Keeps drink cold all day even if you leave it in the car in the summer heat like I have to during home visits.

My functional medicine doc keeps prescribing this protein shake that's supposed to support gut health and help with detoxifying (OptiCleanse GHI). I finally realized that I might not find it so annoying, if I could find a blender bottle not made out of plastic. I mean, what good is detoxifying, if one is also consuming nanoparticles of plastic? So, I went searching on Amazon, and voila! ... the Pursuit Premium Shaker Bottle! Not only is it made from stainless steel, but it's also insulated.The only thing I don't like about it, and the reason I took off one star is the plastic agitator. Not only is it plastic, it is also stationery. The makers think that this is a plus because it won't make as much noise as the typical, moving, stainless steel ball; and according to many reviewers, the plastic agitator is enough to mix their protein shakes. Unfortunately, it does not mix the OptiCleanse GHI. It left it rather lumpy, even after shaking vigorously for a few minutes. Fortunately, I still had the stainless steel ball from my old, plastic Blender Bottle. I found that removing the plastic agitator and using the stainless steel ball in its place was able to break up the lumps in my rather thick protein shake. In fact, it's so thick that the ball does not make much noise on the stainless steel. It's only when I am rinsing it out that it gets rather noisy. And the ball does not appear to be digging up the plastic on the lid. Yes, the lid is plastic. Apparently, as with most things in this fallen world, you can't have everything. ;-)

Great quality and has a lifetime warranty you can sign up for , when you get the bottle for FREE

I have four of these bottles in there, harder plastic that you can see through. Today I stumbled across this one which I noticed it was stainless steel. I love stainless steel for all of my smoothies and shakes, from my water and energy drinks, this is good quality. Stainless steel is better for you than plastic. This couple will last a long time and I can’t wait to use it. I’ll come back and update after a week or two and give you my honest opinion of wink what I think. I’ll even make a video to show everyone how amazing these are. Thank you.

Absolutely love this shaker for protein shakes. It’s insulated and smaller but excellent quality and great price!

I love the design and the quiet shaker concept. Unfortunately does not mix my powder which just gets stuck at the bottom. Works well for other purposes though.

Doesn't mix as well as I had hoped. Strainer/mix built in is also very difficult to clean.
