A very convenient shaker, both while running and in the gym.

It's a great shaker that gets the job done. I haven't seen any clumping with protein while using this shaker which you might see with some other products.

I use this one over any of my others! Really breaks down the protein powder, wayyyy little clumps! Love it!!!

I like the screen and it pours easily. But, the whole lid doesn’t seal properly. No matter how tightly I twisted it, it just doesn’t seal right. My drink drips when I shake it. Wouldn’t not waste money on it.

easy to use & does what it was designed to do

At the end of the day, it's a shaker bottle and it delivers protein to my mouth BUT I was disappointed with this purchase. Shaker bottles are available everywhere, for affordable prices. The reason I purchased the Myprotein shaker was because it says "Myprotein" on it. However, the logo began to rub off within the first 24 hours of use. No, I didn't wash it or abuse it, it simply rubs off on my fingers and makes everything blue. Disappointing.

I have about 5 of these shaker cups now, which I use daily for about a half a year and have never had a leaking problem. Instead of a blender ball it has a screen that does a great job making sure you don't swallow any chunks. The only problem is that the logo does fade off after multiple washes. For the price you can't beat it and I find myself using these over the 10 dollar blender bottles!

The bottle mixes decently well but does leak with a watery mixture in it when you hold it sideways (as if you're drinking it...). Also the cap design is quite annoying as it tends to stay near the opening when the cap is off and if you plan on drinking from the bottle then this cap will be touching your face in an odd position. This is really quite annoying and frankly you will look silly drinking from this. The bottle is cheap and is probably constantly on sale, so I would only suggest this if you use this to mix your shakes and then put it in something else.

Super disappointed in these shaker bottles. Purchased multiple bottles, only to find they leak when on their side or if filled up into the blue top (usually do this with water). If those issues aren't a problem for you, then awesome. The grate system adequately breaks up clumps. It does create a lot of foam though, so I recommend waiting about 10 minutes before drinking.

You get what you pay for with this shaker. Decent build, but I've had plenty of leaks while shaking it. Cheap shaker...gotta expect it
