I have four Nikon lenses and three of them came with good 'reversable' hoods that clip to the exterior of the lens casing. These are all wide enough to avoid vignetting and, importantly, the lens cover can be fitted 'inside' the hood when the latter is in position. Moreover the camera is unlikely to be damaged if the hood is 'knocked'. Unfortunately none of this can be said of this 'flower petal lens hood'.
This hood screws onto the thread for lens filters and so can be fitted to the huge number of lenses (many of old design) that do not have 'dedicated' hood mounts. Why the 18- 55 'kit' lens should be one of those is beyond me- it must be the most commonplace of all Nikon lenses.
The hood usually screws on ok, but if I tighten the locking ring it can be fiddly and difficult to remove: for obvious reasons I do not like to 'force' plastic threads. To my mind these threads are only suitable for (and usually only designed for) fitting filters and I'd rather they do not appear on cameras at all. Most plastic threads tend to 'bind' and the material expands in an irregular fashion when warm, attached items thus becoming hard to remove. Metal expands as well- but it is much less likely to cause damage. Moreover If the hood takes a knock that could damage the plastic thread and thus ruin the lens.
Since the thing cannot be reversed when not in use you are obliged to stow it in a pocket before the camera can be placed in its case, which is a nuisance. Frankly I'm reluctant to fit this hood at all.
