Got the sleeve despite the negative reviews ("lights" very weak) bought. Unfortunately I have to agree that the Schutzülle is off. After a long exposed to direct sunlight can indeed recognize a slight effect, but this is by far back below my expectations. I have beautiful acquired similar items floureszierende (NiteStick) and assumed that the protective sheath similarly well "lit". Although "reflects" the shell under UV light very well, but not without.
The fit is given, also smell the shell not to plastics or other chemicals.
Since the glow was my purchase criterion, I can give NJR three star.
