It's a great shaker! I love the sleek matte design, it holds up almost 1L. Though, you definitely need to put in effort to completely mix up fruit, for example. 5-10 seconds will work with only really ripe bananas and/or berries. But otherwise I love it.

Brilliant bottle beats the old standard design by Miles

Good: - Extremely lightweight - Powder does not get stuck anywhere as there are no corners - Design is sleek and aesthetically pleasing Bad: - The sliding lock mechanism would probably loosen over time and would result in leakage when thrown into gym bags - The liquid measurement at the side doesn't make too much sense as the bottle is opaque and you can't tell the liquid level anyway - The handle by the sliding lock probably won't be able to handle fully filled bottle's weight. It feels stiff and the plastic doesn't seem like it can hold Overall, I think the bottle is not a good choice because I am all about the leak proof caps and I do use my bottles frequently on a daily basis. This does not seem like it can withstand the pressure of time and a couple more washes. If, however, you are just looking for something to mix your powders with and to take to the gym, this would suit you just fine.

Good price considering the discounts that MyProtein often carries. The bottle is made of liquid repellant plastic, so you'll be able to drink as much of the shake as possible. The bottle doesn't have corners, so no powder will be stuck inside. Really easy to wash bottle as well.  The lid is very tight, though after a few uses it seems to be a little looser when opened. Hope it holds out well in the long run. 

I really want to like this, it mixes well, I like the slide top so I know it’s closed, but the threads are absolute garbage—absolute garbage. It’s impossible to get this thing to close correctly, shaking it over the sink making a mess, ruining all my favorite shirts trying to drink out of it. On top of that it’s not cheap. Don’t do it.

Best shaker I have ever purchased. Works perfectly and leaves no lumps. I have tried mixing soft fruits and the shaker blends them perfectly. The special design gives it an extra touch and the finger loop makes it easy to carry it around. I would definitely recommend this shaker to anyone.

I was a bit apprehensive at how well it would blend protein with it not having a mesh grid or a metal ball but I was pleasantly surprised! It mixes the MyProtein Whey Protein extremely well. Just make sure you give it a good shake, like you would mixing a cocktail and you'll be good to use. The quality of the shaker is really good! The lid is completely leak proof and with the matte finish, it feels and looks really nice too! Because of the shape, it makes it WAY easier to clean too as there are no edges inside! Honestly love it and this is no my go to shaker!

I don’t completely understand how it works, but this shaker is a revelation. Mine arrived yesterday and so far I’ve put berries and banana in and shuck, after 5-10 seconds the banana and berries were complete pulp, I then mixed in my water and protein and shook for a further 5-10 seconds, everything was mixed perfectly. Two of my friends have already made orders for this product. I also tried mixing peanut butter into my choc shake and again it worked perfectly. Extremely easy to clean. Anyone complaining about lumps clearly doesn’t know how to shake properly or is using terrible protein. Absolute game changer.

In my opinion this shaker looks good but is over priced for what it is and what it does. It claims that no mixing ball or mesh grid is required. This is not true, I made a protein shake and it was filled with clumps and bits, I even added a mixing ball and it was no better. Save yourself the money and just buy a standard shaker. If it’s not broken, why fix it.

Love the fact that the shaker doesn’t have the kinda stereotype shape. The matt finish outside just feels amazing! The little handle just made it easier carrying around during my long walk today. Didnt try to see if it mixes well with soft fruits, but absolutely fine with whey protein and water/milk. Tested for any spillage (think thats the word) absolutely fine (just make sure you close it well).
