I own 2x Einstein Flash units and they perform flawlessly. The love the clear color display on the back that lets me truly fine tune exactly the light I want in each session. My shoots are primarily studio settings so I don't require the battery system that seems to be the rage today. That just seems to be another item to break or need replacing just when I need it. Highly recommend th Einstein flash.

Great unit needs upgrade
Have used these for 7 years now, but still hoping and waiting for an Einstein II (LED modeling light and Alien Bee type adapter mount).
What's taking so long?
