As I mentioned in my post, having been "pinged" by friends, there is no doubt that these things work. Considering the low cost, it seems that these should be standard gear on a RIB...
Well that kind of depends upon the type. The biggest problem occurs with the more budget end of the reflector market (see picture below). If used as seen in the picture, with one corner uppermost, this will not work very well. Sadly this is exactly how I've seen many reflectors aligned (particularly on mast heads). In order for this reflector to work well it needs three black corners uppermost in the "catch rain" position i.e. lent at 45 degrees to its pictured orientation
Now I've not opened up one of the encased reflectors (something like an Echomax EM230) but I suspect that they contain a stack of smaller reflectors all in the correct orientation. Certainly based upon their reported performance this would seem to be the case.
However my reason for the initial post was to alert users of the simple uncased type of reflector that its alignment is critical to its functionality.
