I have been working with Shen Rui for over a year now and it has been a very great process. The products are of amazing quality and the service, delivery, and customization really brings everything together nicely. Couldn't grow without them. Looking forward to a long term continuous partnership.

This is hands down the most satisfying hearing aid supplier I've ever worked with in China. What makes them stand out is how seriously they take certifications, product quality, and delivery service. Unlike some smaller factories that slash prices but forget this is medical equipment needing real responsibility towards people with hearing loss, Jinhao actually cares. I really hope we can keep this partnership going strong for the long haul, and honestly, I also wish things between the US and China stay stable – it’s better for business all around
