MacBook Pro 16-inch, 2019 Model --------------------------------------------- System Configuration: 2.3GHz 8-core Intel Core i9 processor (9th generation, Turbo Boost up to 4.8GHz) AMD Radeon Pro 5500M with 8GB GDDR6 memory 32GB 2666MHz DDR4 memory 1TB SSD storage 16-inch Retina display with True Tone Four Thunderbolt 3 ports Touch Bar and Touch ID Backlit keyboard - Japanese (JIS) --------------------------------------------- I have been using this as my main machine for a long time, and it has worked without any problems until now. It has a corresponding amount of wear and tear, scratches, and dents. I spilled juice on the keyboard and replaced some keycaps and hinges myself. There are no issues with the feel of the keyboard after the replacement, and the response is good. The replaced keycaps are almost indistinguishable from the originals unless you look closely. I have removed the bottom cover once and cleaned around the fans, and I removed and reattached the battery at that time. I don't think there are any problems with battery life afterward. I often use it while connected to the power supply, so I haven't charged and discharged the battery much, but I haven't replaced the battery, so it may be somewhat degraded. The box is gone, and the only included accessory is the power adapter (96W). I cannot ship on Saturdays, Sundays, or Mondays, but I can ship within 1-2 days on other days.
