I've got one of these. I use it and the original battery interchangeably. I keep a charged battery in my camera case and just swap out when the in-camera battery gets low. I've noticed no difference in the charge length between this one and the original. It's a deal.

This battery was obviously better priced than the on the OEM site. It was also higher capacity than what came with the camera. It works as advertised. I can find no faults.

I bought this battery for my Nikon D40, and it lasts just as long as the original. It holds its charge fine, fits in the original Nikon charger easily, with no issues. And you can't argue with the price, at about 1/3 of an original Nikon battery it is a bargain.

Not the original brand name battery for my Nikon D5000.
This one works as well, if not better with its 2000 mAh and for way less money.
I use two of them in a battery pack on the bottom of my Nikon, and it is just great value for money.

I have a nikon D60, I went on a four day "photoshoot" and had the battery in the camera to test it out. First it charged in the original nikon charger, the light blinked when charging and stayed on when it was done charging just like the nikon battery. I purposly left the camera on while I was out taking pics, the camera was on for no less then 4 to 5 hours a day and one day I had left it on close to 7 hours and still there was three bars showing on the battery Icon. I cant forget to tell you that I took about 400 pictures with just this battery, I was very impressed with this battery and I still am.
Good product at a good price.

A very reasonable, cheap alternative to the costly Nikon battery. High capacity and has been performing very well for me for almost 6 months now. Never had a leak or so in a wide range of climates and temperatures.

Recommended.

No issues using it with my D60, or charging it in the Nikon charger. It remains to be seen how it holds up over the long term but it's fine for now (2 cycles), and is a thrifty alternative to the brand.

Just bought this and used this for about 2,500 photos without having to recharge on my D40.

I was at the beach when my original battery went dead. I put this one in and took over 1000 pictures and still have lots of battery left. About 100 of them were with flash. Most were on manual focus so I'm not sure how much drain I saved on it there but bottom line is I recommend this to anyone.

I'll put it simple: fits *perfectly* in both camera and charger, powers my D5000 considerably longer than the original battery, and costs 1/3 of the price. What else?
