I own four of these units.  The specs are very appealing.  Nice having the battery built in for on location shooting, etc.  Overall I am actually quite happy with them except for one thing.  Sooner or later you will get a "pop" and a puff of smoke and it won't work.  Something faulty in the circuitry of the motherboard.  This same thing has just happened to the THIRD one out of four.  I was in the middle of a studio session.  The light was on the stand.  I went to turn it on and "pop!"  

So now I am looking at a repair estimate  (it took a month just to get the estimate)  for $.   That is more than half the cost of a new unit.   Not sure what to do ... (the estimate says I have to pay a bench fee if I refuse 

It will die on you

It's a good light but manual power only goes down to 2. If you want lower power for baby photography etc with wide apertures it is too powerful unless you make add on extra diffusers ( it was still too powerful with a softbox for me.

Powerful might not recommended for baby photography

Best flash I ever own!!!! Nice Even Light and With Hss!!!!!!!
