Dear Customers：

Due to the increase in electronic components, metal raw materials in the semiconductor industry chain recently, and the severe shortage of supply, Wattsine needs to pay higher procurement and other costs, which eventually leads to a significant increase in production costs.

In line with the business philosophy of honest service and sustainable development, Wattsine has decided to make appropriate adjustments to the prices of some products starting from May 10, 2022.

The rate of increase is as follows:

As always, we are committed to providing quality products and service to you and appreciate your continued support. We hope to get your understanding for this price adjustment, thank you.

Best wishes

Chengdu Wattsine Electronic Technology Co.,Ltd
