I have both the Tripltek and CrystalSky Ultra tablets. Since I sold my M2Z the CrystalSky has been nothing more than a paper weight in my hobby room as it does not work with the Fly app and my Mini 2. This is due to the fact that the CS is 32 bit and not 64 bit and therefore not compatible with the DJI Fly app. However since the release of the SDK package Litchi which I purchased several years ago can now handle the CS so win win situation for me. Anyway yesterday I flew the Mini 2 from my favorite site using both the Tripltek and CS tablets. Surprise surprise the CS won hands down with it’s 2,000 nit screen which was really clear and bright. The Tripltek with it’s 1,200 nit screen was acceptable in the bright sunshine but the CS Ultra was excellent. I am really pleased that the CS has come into it’s own again thanks to the SDK package and Litchi.
