After using an IMac, since 2007, it was time for an upgrade; thanks mainly to third party vendors. My old iMac could not be upgraded to Sierra.So, I found this deal. It is a very nice machine, for under $1000. It came well packed; double boxed, so it will survive UPS. The machine looks brand new.It came with everything you need Super Keyboard, Super Mouse 2, charging cord for the keyboard and mouse. The keyboard and mouse were already paired. Turning it on, I immediately could tell is was a much faster machine.I used the Apple Migration Tool, and had everything on my old machine, moved over to the new one. Also, I upgraded it through Sierra to High Sierra, to be current. So far, everything I use, software wise, is working fine. Internal speakers are really good. Also, the 4k screen is a real plus and looks great.I did purchase a two year warranty, just in case. But, based upon my experience, so far, I think I will get a few years out of this.
