+ Delivery works in the usual unproblematic way.
+ It is a lightweight plastic device by (used on a SB-600) an acceptable fit.
- Unfortunately, the SB-600 does not fit in diffuser plugged in the included carrying bag. So, you have both parts separately transported or kept what I call "sub-optimal" for holding. But that is rather on the "size" of the carrying case of the flash unit and does not lead to the devaluation of the diffuser!
+ The photos that you make using the diffuser, however, compensate for this situation again. The flash illuminates evenly. Ugly Shadow are neutralized. The colors look very natural. I'm really excited.
Conclusion:
Who wants to optimize its use of flash photos made thereunder, can not avoid the purchase of the diffuser. With the purchase you make (despite the price) nothing wrong.
