One of the questions we get asked the most is how do we organize screws for iPad Rehab mail-in repair service. These little phone-sized magnet trays are the answer! Each device that comes in gets filed in our queue with it's own magnet tray labeled with a sticker to match the device bar code. During disassembly all the screws, shields, SIM, etc go into the personal magnet tray that stays with the device at all times. We use iPad Rehab magnet trays for EVERYTHING. Sold as a set of 5 in various colors.
