The included wrist strap with stopper is very practical and the use I would recommend to anyone. If the camera is not balanced, they skin otherwise rapidly. ;-) We have mounted with a screw on the housing to tare a piece of stainless steel with hole. The thread is a standard tripod socket, therefore you need the appropriate screw. The screw can, however, be solved with time. So every now and then either tighten or take precaution spare weight and bolt.
Through the diffuser of the flash is well spread and the image beautifully illuminated. To stow the protected housing I had initially ordered several camera bags at Amazon, because I was not sure what would best fit without being unnecessarily large and bulky. In the end I opted for the Mantona Colt SLR camera bag, in which the housing fits very well.
Now for the big drawback:
As described by another buyer, the small scroll wheel (Einstellungswahlrad) to the housing can not be operated. This means that in modes M, Av and Tv, the aperture value and shutter speed can not be changed. But which are essential if you want to scan, for example, small, fast-swimming fish. One can avoid this problem a little while by land already meets his preferences and works with various camera modes and possibly adjust the isovalues, but it goes much of the camera potential and flexibility is lost. So if you want something more professional photograph / manual, should decide the same for another camera may be.
