This is best refurb, took this company to make it right. 3rd refurb attempt for a bday present. 1st one the keys were sticky like 1980 Apple, it was bought from Chrome Source. 2nd battery need service upon initial startup, it was bought from Prime Souce.It took a true computer tech. This one is amazing. Keys are like butter and battery has lasted over a week on 1st charge. I'm so grateful for this company actually taking the time to correctly refurbish and quality control their products. I highly recommend this seller. Best refurber so far. Thanks so much, I'll buy again around Thanksgiving for a Christmas present.
