Ok, 12.10 for a piece of plastic, but if it does what it does ... but up to now. I do not see any significant difference to the flash unit with fold-down wide-angle diffuser and this diffuser except that this diffuser swallows flash output and can lead to problems under the warranty. I think it makes more sense between wide-angle diffuser lens or a softbox or similar to choose to choose as this intermediate step. I have realized this after a few test photos and packed the article again. But that was okay, the diffuser, there are 2 stars.
