1 star deduction (out of 5 stars) because:
- I would like to see an internal diffuser
- Small flash (eg Canon Speedlite 430EXII + mounted radio receiver, eg Yongnuo 603CII) is not enough of the flash due to design into the light shaper. For large flashes (eg Yongnuo560-III), the problem does not exist, especially since you may proceed due to built-in radio receiver even without 603er.
