“Vismicro comes of as an Amateure. Even though he seems to have the tech knowledge to design and build the specified circuit, it was a lot of work to make sure he delivered the requested design and files, and worst answered relevant questions in a timely/clear manner. This is in sharp contrast to the other contractor, who has been nothing but professional, working on same project independently.
As such if you looking for one-of circuit design project, he is probable be fine. However, if you looking for something that's geared towards mass productiont, look elsewhere. In the end, I just don't trust that the design he provided is the best for mass production (BOM is over twice as requested etc...), and thats why I hired 2 independent contractors for project. One of them should provide a satisfactory design.”
