This shaker is excellent quality and mixes the protein shakes well!

Not the worse shaker I've had, will definitely last longer than any plastic ones that get smashed and broken. The fan blade type shaker in the lid isn't as effective as others I've used, and I've resorted to using a spring ball as well to make sure my shake is fully blended.

The metal shaker came free with a recent purchase of mine if I spend over a certain amount of money. It works as intended and is useful for mixing my protein powder. The cap seals on good as well. The cap is somewhat easy to clean, but overall it is a good shaker cup.

From all the shakers I've had over the past 5+ years (mainly plastic), I thought I'd treat myself with this metal one, and early doors it was nice, felt like a nicer product. But a few months in, and considering the gyms have been shut for a few months so it wasn't even used for 1-2 of them. The lid has snapped off. Think I'll stick with the plastic stuff

Perfect consistency shake every time, also keeps it nice and cold! 

Regarding the blue colored part of the bottle, does it come in black?

Brilliant shaker so much easier to clean as no addition parts in the lid that you usually have to take out and wash. This shaker has it built into the lid making it so much easier to clean.  Great seal and very easy to wash. Very happy with this superior design. Best shaker I’ve got and there are quite a few in the cupboard.

It's durable. Will certainly last a long time. Doesn't leak like most other shakers. Very easy to clean. What more can you ask for?

Good taste and different flavours and options if compare with other brands
