Upload & Sell: On
If you're looking for a Nikon DK-19 eyecup, don't buy this one. http://www.ebay.com/itm/190711513039
I bought one early this week, and today I got an eyecup that is not Nikon, not brand new, not a DK-19, and doesn't fit on my camera.
eBay doesn't even let me leave a neutral or negative feedback for this "PowerSeller" within 7 days of purchase. I'm now waiting for the seller's response.
It may not be a huge amount of money, but I think no one wants to waste money/time on this.
