I can only agree with the enthusiasm of colleagues, but as that's beyond me going financially. 1.99 and shipped free, after testing on the D 5100 and D 5300 I can not tell the difference from the originals by Nikon, but I had paid 29. That's why I've already ordered one, because I've always liked doing a replacement battery. One can not go wrong, because even when not functioning, the complaint would not have been worthwhile.
