Ordered a "Certified" iPhone 14 Pro Max from Apple's Refurbished store on 30/05/25 (a replacement for my son's 2nd Gen SE). Received phone on 31/05/25 and set-up on 01/06/25. When testing phone, immediately noticed that video playback was faulty (lots of random, flashing red pixels). Visited Apple Genius Bar on 02/06/25 which confirmed problem with camera and offered to repair it or issue refund. Had no confidence in this "faulty" refurbished unit so accepted refund.Ordered another "Certified" iPhone 14 Pro Max from Apple's Refurbished store on 04/06/25. Received phone on 05/06/25 and set-up the same day. On 11/06/25, my son was unable to turn phone on (white Apple symbol kept recycling on and off and unable to access "face ID" screen). Visited Apple Genius Bar on 12/06/25 which confirmed problem with iPhone motherboard and offered to repair it or issue refund. Had no confidence in this faulty "Certified" unit so accepted refund.I had previously told my son that getting a refurbished iPhone from the Apple Store was like getting a brand new iPhone. I've had to apologise to him and acknowledge that I was totally wrong. Sadly, I will not be ordering a "Certiified" iPhone (or any other Apple product) from the Refurbished store again.
