I have one and find it to be a good and very accurate meter both when I shoot ambient and or flash. It will give You both readings for flash and a indication of the ambient light when shooting with flash.
One of the flaws of the meter - as I have heard - is that the PC-sync-socket is just soldered on the main board. This can/will cause the PC-sync-socket to come loose. Mine has that problem. Not incurable by any means, but You have to open the meter - which I havent bothered to do yet.
