Can not fine any information about this company. Be cautious, michael.

I have offered my colleague in Shanghai to visit their warehouse in Shenzhen and they agreed. They provided me their address and it came up in a Google search. I confronted them with saying I think they are a scam company, then they sent me several emails trying to ease my mind. They also agreed to send a small amount of product to first try out and then order the rest. Of course they only accept t/t, and I am still leary. I do a significant amount of business in China, but never with these suppliers. It may be a mistake, but for a couple hundred bucks I might still give it a go. What do you think?
