top plastic part is very difficult to clean. opening tab broke off, on two shakers. not a good design

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. 

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.

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 

This shaker it’s not very good, it keeps the drink cool to an extent but doesn’t mix.  Wouldn’t recommend 

I was disappointed with this shaker. It leaks quite a bit and the measurements on the side are really random numbers. I love the plastic shakers from MyProtein so I would definitely recommend them over this.

This shaker is good quality, but prioritises Oz over ML. So if you're from the UK I'd only recommend this bottle if you're needing to measure out exactly 443ml of something. Otherwise avoid.

This beaker is one of the best I’ve owned. Blends effortlessly and keeps drinks chilled. Would definitely recommend
