Experience with Alibaba Manufacturer

Hello,

I’m interested in using Shenzhen Sinorise Technology co ltd to manufacture my product through Alibaba (small piercing; not overly precise machining work). Has anyone used their services before? They have a low MOQ, reasonably fast lead time, are a verified seller and have multiple certifications. Anything else I should look out for? This is my first time using a manufacturer for my product so I want to be better safe than sorry.
