The T-shirt fabric is relatively thick and feels good. In a small side pocket at the bottom you stowed the "remote control", which is connected via a flat cable with the light unit on the chest. Four commercially available AA batteries fuel the party fun. On the small black box, which is about the size of a cigarette box, you will find a removable clip made of plastic, which allows you to attach the thing to the belt or elsewhere, an ON / OFF switch as well as a scroll wheel for controlling the microphone sensitivity , With a plug, the control unit of the lighting unit can be separated. The plug connection is stable and accidental unplugging unlikely. Through a small hole in the fabric cable leads as to the light unit. In this case, to the design of a speaker, the sound can be controlled to flash a wreath. Looks very cool. Incidentally, it is no LED. Behind the subject hides an electroluminescent film, how to use it also for the lighting of digital watches. Since this system is untenable as long as specified in the description of LED lighting, there is unfortunately a point deduction for a non-matching product description.
Wash and iron inside of the T-shirts are not a problem. And the glow effect is definitely an eyecatcher not only at parties. The battery box does not interfere with the dance and the envious glances of the unlit Rest Guest are worth gold.
