Easy to use, attach & detach. Great performance. Doesn't allow the useless light to ruin your picture. And also acts as a shield for your lens in case of minor accidents. Spectacular product by Nikon. Screw the non-branded lens hood. Go for the Nikon HB-45. I'm sure you're gonna love it.
What else do you need to enter the SLR World? It's a perfect companion for My D3100. Just Received it few days back and fits perfectly with my D300 18-55 AF Lens. Still waiting for the right time to try it in outdoor, will get back to you on that later. Bye for now,,Xheers
