As inventors of Vortex Mixing Technology, a genuine PROMiXX product guarantees quality and performance. 
PROMiXX regulates all listings on Amazon to ensure products are genuine, so you can buy with confidence. Make sure you choose a Vortex Mixer that carries the PROMiXX or MiiXR brand logos and be cautious of imitation products that do not carry this stamp of quality.

With the MiiXR+ Stealth you can expect:
 Lithium-poly rechargeable motor unit with device-charging capability (with enough power to charge your phone and mix your shake) 
 BPA & DEHP-free Tritan bottle
 Ergo sport style lid (guaranteed not to leak)
 Airtight NUTRiPOD for supplement storage

All of our mixers are intended for powdered nutrition and liquid ingredients. Get creative and try adding powdered peanut butter, pre-workout, flaxseed powder, cinnamon and so much more. You could even use your shaker to mix your eggs ready for scrambled eggs or mix baby formula. See what you can create!

Add the liquid of your choice to the bottle (250 - 400ml); push the button to activate the vortex; pour your powder into the spinning vortex; push button to turn off once your powder has fully mixed (about 10 seconds) and enjoy! For the smoothest shakes always remember to start the vortex BEFORE adding your powder!
