Rating: 5/5 Looks and feels brand new. I could not even tell it was refurbished. June 1, 2022 Looks and feels brand new. I could not even tell it was refurbished. Only issue I have is that I have a severe keyboard lag when I use it with bluetooth. I am using a brand new Apple Magic Keyboard. When I connect the keyboard using the USB wire everything works great. Seems like some bluetooth issue.

Reviewer: BraveFalcon-17811

Rating: 5/5 Smokin deal May 30, 2022 I ordered on my phone and it was easy. However the checkout box stayed front and center while I was trying to get the zero interest option, I accidentally clicked check out instead of getting to the window with the special - so I was disappointed in that, but the deal was awesome and customer service was great after the fact even though they couldn't switch payment type. I am happy with my experience.

Rating: 5/5 Macsales.com (Other World Computing) continues to provide outstanding service and products. April 8, 2022 The website for configuring the computer was clear and easy to use - not an easy feat as some options are mutually exclusive from the manufacturer. The order process was smooth. And a representative contacted me when the product shipped, to make sure that we would be around to sign for it. The computer showed up on time, in great condition, and all the purchased upgrades were in and ready to go. Always a pleasure dealing with the folks at Other World Computing (OWC).

Rating: 5/5 27" going out with a bang April 7, 2022 This iMac replaces a 2015 27" 4.0 Quad Core iMac. As this new one is the last iteration of the 27", I'm pleased to have gotten a good deal on it as it will be my last one. I've always loved my 2015, but this upgrade was definitely worth it.

Rating: 4/5 iMac update purchase February 23, 2022 This iMac arrived in perfect condition. Memory (32 GB) and SSD (500 GB) were installed as ordered. I had it delivered to the local UPS Store to avoid the "porch pirates" that have recently been plaguing my city. It came with Big Sur so I wiped the SSD and installed a clean Monterey OS. Then used Migration Assistant to move the data off the drive in my old iMac (27-inch late 2013) to my new (27-inch 2020 - current model). I've been using it now for several weeks and so far it has performed as expected. I'm satisfied with the purchase. My only suggestion would be to have included some advice for setting the machine up. I had to call my son for some help in the setup.
