I picked up a ?fasttech? one, and it looks maybe a bit better than the reviewer’s version. It’s less scratched up, but my first impression when I opened it was, “Yup, this is the cheap version.” Actually I quite like it as a cheap proof-of-concept. I’m kind of thinking about pulling it apart to see about shining the internal silver part, but I’m not sure if the risk of breaking it would be worth any gain. I’ve also never used the original one, so I’m not sure if there would be anything to gain. I do find subjectively so far that the light shines a bit more than it glows, but that’s fine for me.
edit: Was it really fasttech one, or dx, banggood, other… I can’t seem to find the order anywhere
