Build quality seems fine after a few months of use. Gives a decent amount of light for 5 Watts. Solid bracket and screws.
Programs are OK. Needs to be fairly close to an audio source to react to audio.
Angle is not supertight, but can easily be positioned a few meters (4 to 5) away from a 50cm mirrorball.
Remote seems rather weak, buttons give close to no feedback, handle with care.
