I have to sell this as it's not compatible with M1 Macs. This is 32-bit software, so it won't work with OS Monterey. But it will work with any Intel Mac not running Monterey.
This is all I needed to calibrate any monitor successfully, and I only used it maybe 5-6 times.
The whole kit is there: calibration unit, CD and instruction manual.
Takes about 15 minutes per monitor, and it works on any monitor, does a great job. It's much easier to print correctly once your monitor's properly tweaked.
