Of course I've only had it one day but so far I'm very pleased with it. It replaced my 2014 Mini. Graphics are awesome running on a 32" 4K Dell UP3216Q at 60Hz. SSD is getting about 2800 MB/s R/W which is great. Around 25800 Geekbench. No issues some others are posting about. Coil whine, heat, T2 related crashes, etc, etc. Mine is running rock solid, quiet and very smooth. i7 model with 1TB SSD and 32GB Crucial ram, 10.14.1.
