The original spend more worthwhile

I had initially bought the cheap, also allegedly "original" version. The result: color variations, deficiencies in the accuracy and unfortunately considerably less capacity than promised.
Quite different the battery-reviewed here: it shows measured 5422 mAh and ensures that my white Macbook again as long hold out, as the first day.

I think the investment has paid off for me. The low variant would only come into question for me if I did anyway connect the Macbook permanently to the mains.
