Query: It better be diamond encrusted

Never before have I felt more gouged by Nikon than after buying this. It couldn't possily cost more than $20 to produce this thing, I can't imagine how Nikon can justify this price. But, what can you do? If you want this battery, you're stuck.UPDATE 8/19/2010I recently purchased an off-brand from Adorama. It looked very similar to the Nikon brand, and it charges both the En-El3 and En-El4 batteries. Cool, huh?Nope, the Adorama knock-off charged reliably to 18% each time, then stopped. EVERY TIME. I guess Nikon is the only way to go. For this reason alone Nikon gets one star.
