I like the concept so much that I bought the earlier white version. In less than three months the unit failed completely and NiteFlux completely failed to stand behind their product. I expect these lights work for most people and they make a lot of sense as a be-seen product. But after numerous emails to NiteFlux service over a period of months in which they said they'd replace the faulty light but never actually did anything, I can't recommend NiteFlux to others.
