As we all know, the COVID19 is serious in the whole world. We need to keep the safey distance with other people. So the wireless

window speaker seems necessary in the bank, hospital, clinic and pharmacy. We can put the Mic in the window, and staff stay in the home. Once the customers come, we can talk via the wireless window intercom system. 
Stay safe and keep healthy is the most important thing in the COVID-19 period. 

Let's check some feedbacks from KOQI/YCALL window intercom

1,We use it at our office to screen persons from entering our office or to receive packages. It was almost impossible for us to communicate with visitors without this device. It works 
perfect for us. Easy to use and easy to install. We are located in a hot and humid area, the stickers provided didn't work for use. We had to use a silicon base adhesive.   from  Mariubz
2,Works perfectly for us, it was easy to install, no need to keep charging batteries. The unit works somewhat well. Our customers need to get right close to it for it to work correctly. If 
they are not right next to it, then we might as well not use it.
3, I bought four of these windows speakers for two of our stores (check cashing place) the sound is good, employees are happier now they can hear our customers better. A little interference 
at first but we managed to fix soon.
