When used as part of a video shoot, the lens hood snaps VERY well unlike some reviews I've read and have a little scared at first. Simply orient the check for clipping when tightening, and the mechanism snaps very well. There are benchmarks for this. The sunshade keeps well in place. The plastic is rigid and reassuring design. The design is very similar to the original Canon.
In short, a very good product for the price. No hesitation !!
