STS EDUCATION can take delivery of your devices and refresh them with our nine-step process. This service includes external and internal inspections, cleaning, benchmarking, formatting, testing, and quality assurance check; we return your devices with our guarantee. Also, during this process, we can upgrade your devices by adding an SSD, increasing memory, and updating the OS to the latest version of Windows. If your devices are visibly showing signs of wear and tear, we can even re-skin the exterior of your equipment.
