I was looking for a metal bottle as a better choice for the environment. This looked like one of the better ones on the market. It was perfect for about 3 months but the plastic cap has now broken and the rest of the bottle is now useless.  Please Myprotein make this bottle with a metal cap, it would be so much better. It’s really difficult to find a good metal water bottle. 

Shaker is of amazing quality and mixing is just awesome... Just counting... 4 as of now...

I have been using it since getting it a few weeks back. It's a great shaker, both utilitarian & pretty.

Terrible product. Plastic lid broke after less than 5 uses. Costs twice as much as an all plastic bottle but the lid is worse.

Positives: Looks good Feels good Keeps drinks colder for longer Negatives: Built in mixer isn't up to the job Built in mixer can't be removed Built in mixer tricky to clean Weird measurements on the outside, who wants to measure out 443ml? Hard to measure properly as you can't see the liquid from the outside. Recommendation: Stick with the cheaper plastic shaker with the spring.

ITS GUD BETTER THAN OTHER SHAKERS...it gives smooth lump free shake

The built quality of shaker is good but the lid leaks alot. I have 2 shakers and both of them have the same problem

Love the metal shaker and the design. Unfortunately after a month of use the seal began to break which means it leaks when shaking/laid down making it absolutely worthless. Spend your money elsewhere.

A great shaker, bought as a gift. Not used it yet but impressed with the quality! 

Decent enough shaker however I mistakenly thought it kept drinks cold but it doesn’t. In fact anything cold makes it impossible to hold as it’s too cold
