We are hesitant to buy a renewed product but the IMac came in pristine condition and securely packed. The system looks like brand new. The Reuse Vendor customer service is very prompt and helpful in answering all our questions.  It was stated in the specs as 8GB Ram but we got 16GB with the system. Out of 4 Ram slots 2 are installed with 8GB each and I still can upgrade Ram to 32 GB in total.  I was able to upgrade to latest iOS(Monterey) . We will definitely buy with Reuse Amazon vendor.
