My renewed MacBook arrived with no cosmetic blemish. However, the computer has between 3-4 hours of battery life depending on how many Safari tabs and documents I am working on. For reference, a brand new 2019 MacBook comes with 12 hours of battery life. In other words, the renewed 2019 MacBook I received came with 25-33% of the battery life of a brand new 2019 model. This is unsatisfactory and makes me hesitate to consider purchasing another renewed product from Amazon or elsewhere. Additionally, every month or so the screen will go wonky with wavy lines. My old Mac started to do that once it was much older.
