Bests & Worsts Reviews from Amazon

I bike a lot. This light failed ~37 days after receipt. * This light needs recharging every night, otherwise the microcontroller decides to turn on the light at a very dim level once the power drops low enough in order to totally drain the battery. Imagine my mood on the second day riding on NYC streets to get home, no rear light at all. * This is not even slightly waterproof, at most water-resistant. You can see the light through the back where the two halves of the product snap together and I believe the product failed as a result of this, having ridden one day without fenders. * Good thing: The customer service was prompt and refunded me without me having to return the product. But they then asked me to click "not helpful" on someone else's review. So... kinda shady. See attached pic.
