I like the bottle overall, it doesn’t leak and is pretty sturdy. But the protein shake odor lingers quite a bit and doesn’t go away even if you wash immediately. Takes soaking for it to go 

Nice Sturdy and durable for long term. Doesn't stink with protein flavours like other brands (post washing)

Was always skeptical about getting the more quality shaker bottles, but I don’t know why.  I have wasted god knows how much on cheaply plastic bottles when for a fact I know this will outlive them all put together. The quality of the shaker is great, no leaks and no shaker ball to lose aswell. I don’t know if it’s just me but it makes cold water taster nicer aswell but I don’t know if that is because of the metal.  Please buy one of these worth the extra couple of quid long term!

Great upgrade on the plastic ones. Well worth the investment. Washes easy. I'll get more of these

Great shaker altogether, does not leak, keeps my drink cool and looks fancy! I think this is going to last a long time, probably longer than most plastic shakers, which is the reason I bought a metal one. 5*

Ordered easily delivery on time and perfect love it

One of the best quality shaker ever had. Thank you myprotein for this amazing product. 

The lid has a built-in shaker cone, which makes it hard to clean. Also, the shaker cap doesn't tightly close, making it leaky if not held upright.

It works great for mixing drinks. I love that it is stainless and easier to clean. The lid is awesome. I wish I had bought more than one now.

As its looks suggest this is a very durable shaker and it doesn't hold any bad smell after so much use of it ... Thanks my protein
