Warrior Supplements Protein Shaker Review – 600ml Blender Bottle Review UK 2026 — Worth It?

A decent protein shaker sounds simple but the difference between a good one and a bad one is felt every morning when you're trying to gulp a shake before work. Warrior's 600ml shaker has earned Amazon Best Seller status by getting the basics right — consistently.

The wire mixball is the key feature. Unlike plastic blending grids or agitator balls, the stainless steel coil actually cuts through thick protein powder, creating a smooth drink rather than a lumpy paste. It works well with whey concentrate, casein, and meal replacement powders.

At 600ml it's the right size — large enough for a generous two-scoop serving with 400ml of liquid, but not so bulky it won't fit in a car cup holder. The flip-top lid snaps shut firmly and has never leaked in our testing, even when shaken vigorously.

Cleaning is straightforward: top-rack dishwasher safe, and the wide mouth makes hand-washing easy. The BPA-free plastic is odour-resistant, so old shake smells don't linger into the next day.

The wire ball does rattle audibly when the bottle is empty, which some people find annoying in quiet offices. And the wide mouth, while great for adding powders and ice, is slightly more prone to spilling than a narrower sports-cap design if you're drinking while walking. Minor complaints for an otherwise excellent everyday shaker.
