Can you believe it? Running on two Energizer AA batteries, my Nikon flash finally stopped flashing after 5 months of on/off usage. Remember that I bought my Speedlight almost together with my Nikon D90. Shot count on my camera currently read 5350.
So, here's my mini verdict. I hardly use my flash, however hard I tried in my daily routine. I was quite determined to get the Nikon SB-900 lately but concluded that I would grossly under utilize it as well.
