This is the first time I have ever purchased a renewed product.  I was a little skeptical but I have been pleased so far.  The computer came packaged in a very secure ridged bubble pack that was protective but easy to open.  The computer itself showed no signs of wear.  The mini keyboard and mouse were included.  I upgraded to the 32GB of Ram. A few lessons I had to learn: 1)  When I turned the computer on the mouse icon and the opening menu were frozen and the wireless keyboard and mouse would not work because they run on bluetooth and I had no way to pair them together.  Fortunately, I was able to plug in my Logitech wired mouse and keyboard and they worked instantly so I was able to pair up the apple keyboard and mouse.  2) The iMac came loaded with Catalina which wouldn't run my music programs but I was able to quickly upgrade to Big Sur which solved the problems 3) The keyboard didn't have the"#'s" key but in my ignorance I didn't realise that the keyboard can be changed for different locations.  I discovered that this keyboard was set to "Britain." but it was easily set to "United States". (Thanks YouTube).  I use two different printers but for some reason I was never able to hook my Mac Book Pro wirelessly to my Epson Artisan 1430 printer but this computer paired right up as soon as I downloaded the drivers. I love the 27" screen.  I'm very happy with this purchase so far.
