A neat and uncomplicated item - once you work out the best way to drape it over your camera, lens, flash and top of the tripod. That process may appear to be so simple it needs no mention at all but this item comes with NO instructions whatsoever - not even the best way of cleaning it or servicing the zips, and that for an important item you will only use in bad weather!
Let me be quite clear, this cover appears to be well made and straight-forward as far as overall use is concerned. It is, however, an item which will ONLY be used in inclement weather and for that reason, once purchased, is likely to be put away (and forgotten) until needed. The lack of simple instructions, therefore, will not be at hand when the user is struggling to assemble and protect expensive camera, lens, flash and fit them all to a tripod in the rain.
May I suggest, therefore, you download and print a copy of the item in use - as shown in this or other, similar, advertisements, and place that picture in your camera bag so that you have a ready-reference when needed. A reminder to completely clean and dry the item immediately after use might also be useful for some...
I hope this helps and that the makers are taking notes!
