They're efficient but severely disorganized and not straight forward. I just put in an order for them to send me a prototype. Came to find out 'everyone' on Alibaba offering that service was the same person lol
There's a very sizeable swath of houston thats dedicated to mid sized Chinese manufactures' but it's completely impenetrable because of the language barrier and lack of organized information. None of them are on Google. I get the feeling that someone among them does what I'm paying someone to do in Asia but I'll never know.
