The LingLong DingDong is a Chinese-speaking Amazon Echo

Its latest digital home assistant model, the A3, looks pretty similar to the Echo -- it's a cylindrical speaker that will respond to users asking for information such as the weather or their schedule. It can play music, or help you take notes and control your home appliances -- pretty much whatever internet-connected system it can talk to. And in typical Chinese fashion, it's priced very competitively at 698 yuan ($100), while adding new features like portability -- it's able to play up to eight hours of music on the go. If you haven't heard of it yet, it's because the company hasn't aggressively marketed its products outside of China. So here's what you need to know.
