Query: Opteka Battery Pack Grip for Canon EOS Digital Rebel

This is a great product for the price 100% satisfied with the grip but the battery quality is a little poor thats why the 4 stars.The single battery that came with my Rebel xt lasts as long as the two put together that came with the grip.If i ever need another grip i would probebly purchase this brand even with the poor batteries.Take away the batteries and its still a good price.
