I've got this exact same set of batteries and charger from them.
I've been REALLY HAPPY with it. I use the 2300mah batteries
in my camera and in my strobe.
(I actually bought the 24 pack and two chargers. the 24 pack comes
with 6 battery cases that hold 4 batteries each.)
I looked at other batteries including "brand name" ones and ones
from Thomas Distributing and decided these were the best bang
for the buck. One of my co-workers did a battery comparison
of these(Powerizer), the Engizier, regular alkaline, and and the ones
from Thomas Distributing(PowerEZ I think).
They all did well, but they Powerizer was within a percent or two
of the performance of the others and was 1/2 or 1/4th the cost
of the others. The "final results" showed basically that the
Powerizers were the best bang for the buck.
If you want to see the comparison test, sent a PM to
ScubaLuke . I'm sure he'd be glad to send it to your or post it here.
