The SC13 is a neat little pocket light, but I really wasn't a fan of all the rainbow ring artifacts from the fresnel optic it has in it. This stuff did a great job of smoothing all of that out and leaving me with a really nice looking and decently floody beam.
It might not be the best value proposition since a roll costs about as much as the light itself but hey, it worked great. Threw a Vapcell H16 in it as well and it definitely makes me want to carry this little thing around more now.
