I just purchased a complete set of gels from Steve last week. These things are awesome. The gels are precut and mount in a few minutes. He sent the entire set labelled with the color name and number code. I am using the gels underneath a smoked Darkstorm lens. I was able to perfectly match my empeg to my dashlights and my friend's empeg to his. I've been using Steve's lenses for a long time and absolutely love them. I highly recommend the lenses and gels. When I get a new digital camera I'll try to post a few pictures of the color match with and without the gel.
