Friend of mine has the NPro/njoy. She got it from her son. I have no idea if this products is along the same lines as say the 510? I see refill cartridges for it, she even has juice, can she just do like we do with the cart and pull the fiber out and refill it? I am not finding a lot of "break down" on the functions of this brand.
Thanks for the help.
