I bought some lights and the light quality wasn't good enough for my use. I asked Athom to return them, I don't know if I got some faulty ones or not. The country I'm in has a law that says that I can return a purchased item in 30 days, no questions asked, in case they are OK.
But they stopped replying. Both in the forums here and through emails.
I suspect they will also delete this post. Beware, don't buy from them unless you're sure about what you're getting.
