Question about Magicshine MOD 20B

This means that you can adjust the luminosity via a (dog-lousy, partly not translated from Chinese) app. However, it has to be said: as soon as the app is connected and the luminosity is set via it, it can no longer be adjusted on the lamp itself until the profile on the app is deleted again. The lamp appears physically high-quality, everything else is junk. I unfortunately fell for it this week in a discounted daily offer from Galaxus, I would keep my hands off it.
