My main worry about this device is that it will, like most modern phones, quickly become useless due to lack of software updates.
They're building it with Android 7, which was before Project Treble[1], so future updates are at the mercy of all the chip suppliers and their willingness to port their ad-hoc drivers to newer kernels.
When the device stops receiving updates, it won't be safe to use on the Internet anymore and things like out-of-date SSL certificates will break things (see e.g. this video[2] for what browsing the web on Symbian and MeeGo devices looks like today).
