韩国采购需求：心率监测器、智能手表、自行车传感器、智能跳绳、传感器数据接收器、体脂秤

I'm interested in placing an order for 30 units of the heart rate monitor. Can you provide details on the pricing per unit, any bulk order discounts, and lead times for delivery? Additionally, please let me know about the available color options and any warranty or return policies that come with the product. It would also be great if you could send me any relevant product specifications and certifications, as I want to ensure the monitor meets quality standards for my needs. Looking forward to your prompt response so we can move forward quickly with this order!
