Protein Shaker Bottle Stainless Steel Sports Water Bottle Shaker Cup with Double Wall Vacuum Insulated, Thermos Leak Proof,720ML(25.5-Ounce), BPA Free (Silver)

Love the styling, kinda looks like a cocktail shaker so when at work chugging frozen smoothies and my mouth goes all numb slurring my speech, I can just pretend I’m drunk.Too bad the stopper has such a shallow click to close, have to be very careful or else it can open up unexpectedly and discharge its contents all over. The chocolate milk incident when I was wearing white comes particularly to mind...Was kinda skeptical pre-order that the shaker spring ball would be of any use but was surprised to find how effective it really is in mixing all sorts of beverages, from protein shakes to semi-frozen smoothies. Do wish it came in a larger size though because I’m a toisty boi and for me, 25oz is just a single serving.Doesn’t keep beverages cold as long as any of the double walled cylindrical bottles in my collection, not sure if that’s because of its conical shape which results in a proportionally larger [uninsulated] lid. But even if I start out with the contents semi frozen and full of ice, after only a few hours all the cubes are gone.

Keeps my shake cold, no leaks in my bag, and I’m enjoying it!!!

These are nice and heavy duty. I ordered two of these and they are holding up well. Keep my drinks cold for hours.
