HydroVessel Vacuum Insulated Hot/Cold Protein Shaker Water Bottle (White) ● 20oz Blender + 4oz Cup ● Stainless Steel Double Wall ● Easy Cleaning Mixer ● BPA-Free ● Workout Gym Office ● Smoothies, Ice

I love this cup. I haven’t used it to shake up a protein shake yet, but I blend a smoothie and then put it in the cup and it stays cold for hours making it easy to drink later if I can’t drink it right away

as others have said it did leak when I first received this shaker cup....but I took out the gasket and repositioned it properly. it was not placed in properly. now I have no issues with leaking at all. it's a great quality item. it just needs to be put together properly by the manufacturer. other than that no issues.

Initially I was swept away by the attention to detail in how well the flip top shuts, the rubberized mat on the bottom, the lack of seems to catch protein inside, and the overall finish.When I went to use it, the gasket between the lid and the cup itself seems to be totally useless as fluid constantly drips around it all over my hands.Hoping the company can send one with a non leaking lid - if it weren't for this I'd give it 5 stars.

So happy with this easy to wash cup and storage. Use it daily as I begin this new chapter on weight lost. Really keeps my breakfast cold when I take it on the go.

I got this product so that I could bring my protein shakes to work and mix them fresh before drinking them. I was a little disappointed at the volume. The dry compartment is barely big enough for 1 scoop of protein, with no room for extra flavorings (I was hoping to do double scoops). The liquid section is again constrained, to the point where you can barely fit 8 oz of liquid plus the powder and have the lid go on without making a mess.I spent a LOT of time shaking up my protein (5-10 min) and it still didn't come out as smooth as with a standard shaker ball. It was still drinkable, but not quite as good.I found that on my bottle, if you attach the lid while its dry then it won't leak, but once you open it to add the powder and close it again, any tiny drops of liquid on the rim will make it leak when you shake it. The closures are pretty basic, so liquid tends to get into the grooves really easily. Also, if you open it to take a drink and close it again, it is prone to leaks. The gasket on mine also keeps falling out (maybe why it keeps leaking?).So in summary, I'll probably keep using it because it is better than anything I have currently, but its just not as good as I was hoping.

My Daughter uses it to keep her shake cold after workouts, she LOVES it!

It doesn’t have a good seal. It started to stink bad so I attempted to clean the rungs and It leaks now. Not worth the money.

This is such a cool concept but terrible implementation. Leaks if not upright, ice melts in couple hours and it rusted within a few weeks. Wasted purchase.
