Prototypes are meant to be molded and refined until it embodies viable set of features, given the present constraints. Prototyping a device is one thing, but refining it to fit the numerous criteria of technical feasibility, manufacturing, and final product design can be challenging.
That said, we are making very good progress. And these latest images show the device at its 4th iteration in its prototype stage. We are getting close, and all we need to do is to pull all the pieces together to make Monbaby into truly integrated device!
