Facing increasingly market competition, your products need to have excellent design and unique features to enrich your brand value and win customers. While manufacturing such product in China could be quite profitable but also very risky.
New product design request frequent communication on technical and design topic, tooling investment, source for the right material and components, and manage the project schedule. Finally, you may still suffered by unexpected quality issues and delay of delivery. Not even mentioned the patent risk: you may be surprised by product with the same design as yours but in another brand name on the market.
