Demb Flash Diffuser Pro Vs Lightsphere Cloud

I am a big fan of Gary Fong's lightsphere product, but I am searching for an alternative diffuser with better versatile that works in different situations (ceiling or no ceiling) and use less power.

I heard a lot of good things about Demb Flash Diffuser Pro and like to compare it with Gary Fong's Lightsphere Cloud.

Test photos are shot with D700 SB-900 manual and manual flash mode.

First Test: bounce with a 30 ft ceiling.





Second Test: bounce with a 10 ft ceiling.





I think Demb Flash Diffuser Pro does a better job on saving flash/battery power and offers more versatile in your camera bag. However, if location has a low ceiling then lightsphere will do a better job.

Happy Shooting.
