Lol, redbuthotter gon' be mad when he reads that. He was telling me how it's the state of the art technology - pinnacle of powerless blending. XD
I dunno if it does anything but it's better than my other 2 year old shaker for sure.
MaxiRaw makes a REALLY good protein powder - very fine powder that doesn't clump. However, MP's whey does clump so I'm thinking the metal ball would mean that the clumps catch onto the metal ball.
I find the maxiraw one with the grate works just as well as the myprotein one with the ball.
And the one with the ball is annoyingly clinky when it's empty afterwards as the ball rolls around... And it can be loud as hell whilst shaking as well.
Well before I was using MP whey protein and water and shaking it. Quite a few clumps.
Now even with my old shaker and MR whey there's no clumps. Plus, MR tastes a lot better. I think MR may have my money from now on... choc orange is ****ing nice!
Just for reference, I use unflavoured MP whey in water and sometimes creatine, nothing else. Zero clumps with or without the shaker/blender ball. But without, it's much quieter, therefore better.
