I typically always buy these computers for our work as they are an older generation, but they work amazing, and they are designed to last forever, 5 to 7 years of use or more. The seller had a great unit and I was extremely happy and pleased with the purchase. The product works amazing and the battery is still in great condition. No defects or anomalies are present with this unit, and I would definitely buy from this seller again 100% recommend! Five stars review!!
