Promixx Neoprene Insulated Sleeve (Black) Vortex Mixers, Shaker Bottles - compatible with Original, Pro, Charge, MiiXR and Shaker Bottle Pursuit

bought a voltrx because its motor was waterproof,it may be waterproof but cannot mix more than one scooop of protein power so i read up on pro mix with its 6 years of development its British so what could go wrong it also fails when adding more than one scoop the power i use says to add 4 scoopsto 750 mls of liquid so i figured 2 scoops to 500 mls would be ok not a chance after adding the second scoop slowely halfway through the vortex disappeared and te undisolved power just sat on top so i gave it a chance i put the lid on and left it running for 5 minutes no change i then tried shaking it with the motor both off and on all i got was a lumpy mess in the end i poured my lumpy mess between the voltrx and th promix and eventually i got a smooth protein shake,so if you have £66.00 and ten minuets.to spare the promix voltrx shuffle is the way to go about the only thing they are good at is cleaning themselvs so in summery dont waste yuor money just get a decent manual shaker and dont be lazy

This sleeve is great if you are taking cold liquids before you mix. I fill the container before I travel to work and i have found this makes a great difference. A must have edition to the promixx cup.

Quality seems fine, it's what you would expect.

Bought as a gift

Worked really well for about a week then just stopped spinning, checked the motor and it still worked just the actual stirrer stopped spinning l, not worth the money. Just disappointed.
