I have worked with Shenzhen Renjia Technology Co., Ltd for nearly a year now and their team, in particular Holly has been great to deal will. I have visited both their factory and office in China, and they are very professional/hard working. The product quality is always great and they really listen to your requirements. I would recommend working with Shenzhen Renjia Technology Co., Ltd. for any silicone based products. They have been able to scale operations with me really well and maintian a high product quality. I look forward to a continued relationship with them. Thank you for the service
