+ Does what it should, + Fits through the generous rubber band on almost all Kompaktbltze + Can be present on the flash housing and slide back, thus also the additional, above-internal Silberfolienrefektor comes at the ceiling flashes into effect + Takes in the camera bag any space and weighs next to nothing - is always there + Reasonable price
- Light distribution is not as uniform as in a fixed softbox - Does not really professionally ;-)
Conclusion: I would buy again and highly recommend it for mobile use
