Installation: Very easy - they are, as the original lamp sockets, clipped into the hole in the boot lid, the vehicle side cable connector fits to one of two separate connections of the light unit (depending on the model, I suppose). A resilient seal is also available. To disassemble easily move around and try to remove the side.
Processing / function: very precisely (z.Vergl .: one of the original parts read only by gross negligent force remove); no problems with the on-board electronics.
Price: It depends on how you are to detail - who also places emphasis on small accents and quality is well advised with this LED Beluchtung.
