Excerpt: The HB-45 works as intended to reduce lens flare, lens protection,etc. I had read some of the other reviews here prior to purchasing and I was concerned by some of the commentary that people had made concerning the "snap on" feature of this hood. After using the hood on a recent trip I can say that the hood works fine. The hood did take a few light bumps and never came off.
Excerpt: The HB-45 snaps on for a perfect fit. Would not consider any other lens hood for your 18-55mm kit lens.Has two spring loaded buttons on each side which must be depressed for removal. No problem. Great lens hood.
Pros: Durable, Easy To Use, Lightweight, Perfect Fit Durable, Reliable
