    Easy process

    Easy to find what I wanted, easy to order. Got it quickly. No problems. All in all a good experience.

    New ProStak

    Love my new ProStak. I replaced an older one that was leaking from the top. The new design is a much tighter seal. So happy. Thanks

    Nice idea

    I got it from More Nutrition, and think it is a good idea. But how it was made, it really annoying.
    The additional boxes are really awful to open. Today I cant open the 150cc. I closed it careful, but it does'nt let me twist the head anymore. Why? Is there a trick.

    All other factors are great. Blender is good, it is safe and nothing wont get out.

    We are sorry to hear about the difficulties you have had with the ProStak. All of our products are covered under a limited lifetime warranty. Please file a claim at and a representative would be happy to look into this for you.
