Customer Reviews
A must to haveGood quality item. It gives faster flash reload and longer shooting for events like weddings etc.
Highly recommendable. I use it on a Nikon SB-800.
Good as a back up power source
I got this Item, worked great. But after just a month it stopped working. I sent it back for an exchange. Was waiting a month to get a new one back. Didn't get a chance to test it yet. I hope it will not break in a month as previous one.
Not what I was looking for.
