"Safety certifiation" doesn't make something "safe". And lack of official safety certification doesn't make something "un-safe".
If you are installing this is a public place (or somewhere you don't live like a rental property, etc.), or if you are worried about your fire insurance, then don't buy dirt-cheap goods from China on Ebay. And perhaps in your country licensed electricians are prohibited from intalling non-certified components.
Would I install one of those in my house? Probably. It looks rather well designed and assembled and I am a DIY geek.
