+/- Light intensity does not change immediately, but soft.
Knobs 1-4 are for selectable intensity. In my opinion, quite unnecessary with the 25/50/75/100 buttons. Did I just saved the lowest setting. But perhaps you can with several controllers build beautiful scenes.
Visually, the box does not work so hot.
This is obviously just packed only fitting to do so because after the top cover is a plate with several screw holes, the attachment without the box on nearly each well allows (big + point). On the box it is simply tightened with two screws and is not particularly locked.
