Voye 003A2 2 Plug-In Wireless Digital Doorbell with Battery (White)

Melody Chime Wireless Door Bell Note: At first it needs time to detect the frequency of the button and doorbells, so try a few times again they will work. We got the items from the supplier, but we insisted on checking the usability of the items, so we installed the battery and checked whether it was working. In order to prevent the loss or parts fall caused by long-distance transport, we decided to add a small staples in the original packaging to improve the packaging.
