The delivery was very quick. After two recharges the battery lasts about 3.5 hours, the charging lights work both on the battery and on the MacBook very well. The color of the battery (white) right footed original, the fit is not quite optimal, the battery is slightly exceeded what not stört- and there is no fourth rubber foot, the foot on the battery is in the plastic housing only highlighted, but so well that nothing wobbles. Who does not interfere with this minimum weaknesses must spend on the original does not triple the money. I highly recommend the product.
