For that price, I bought these.
Amazon.com : Cygolite Expilion 850 USB Light with Helmet Mount : Sports & Outdoors
I have too much crap from unproven chinese vendors to keep giving them money. I would rather spend my cash on a proven reliable, supported american brand.
I just show my local bike shop the amazon price, and they match it, which saved me about $50 on this light. That way I get American quality, a known product, and local bike shop support.
