I simply am not interested in battery powered lights. There have been tons of complaints about magicshine, I'm sure that the failure rate is much higher than that for B&M. I can't imagine gloating about spending so much for so little. And I feel like symmetric optics are irresponsible and I wouldn't ride one on the road unless forced. As far as $5 lights, just wait until the first decent rain and check back. I had a $5 light that died after 30 minutes of rain. I was driving home the next day, noticed some weird light in the back of my car, and it turned out the light had dried out enough to start back up. Thanks, but no thanks.
+1 irresponsible is a very good word choice.
