Unfortunately, the housing and the holder crap!
For casual riders it may hold, but who travels often will have little joy. The bike mount is ruckzuck worn and the lamp then wobbles.
Worse, however, is that the retaining lug of the flap also breaks very quickly. At 2 Ixon IQ and a Ixon the lug is irreparably broken in them all. With a cable tie but you could still very well "fix".
In an IQ also the hinge of the flap but is now dawned, characterized the lamp goes out more often than usual (see other reviews).
Conclusion:
Unfortunately, not mechanically mature :(
Which engineer brings to the holder on the most fragile part of the case ?! One would have the shutter can make on top just as well and all problems would be solved.
