Having purchased the i1Display 2, the Huey Pro and then the Spyder 4 Elite these devices have a pretty finite lifespan of a couple years at most.

If the manufacturer doesn't discontinue software updates for your latest OS the sensors in the devices themselves seem to use fairly cheap plastic which is susceptible to colouration over time causing the calibration's to drift quite significantly.

It might be more cost effective to just have someone calibrate your equipment for you rather than buying another plastic baubel with questionable longevity.
