Yes, *IF* you are *VERY* near the reflecting surface, since
to be effective, the reflected light must be within maybe
1.5 stops of the main light to show - and this is a
difficult level to achieve with the distances and surface
reflectivities generally involved...

Ummm... A good test is to look directly at the flash
with/without the accessory when it is triggered in a
darkened room - the afterimage will show you whether
or not there is a very high level of light from the
accessory relative to the main light. You may be
surprised to find that you see mostly the small flash
in the afterimage, indicating it is doing little in
practice. It is easy to believe things that do not
hold up well after doing simple tests...;-)
