Putting aside the hardware - which I think is a bit cheap-looking (see the seams down the side of the moulded watch band?) - the software is all Google. And by that, I mean it's badly-written. When he finishes the ECG it says, "Data collected". That's not friendly; it's pedestrian, it's cheap, it's written by a product manager who thinks like a robot instead of a human. It also reinforces the idea that Google are just out to collect your data.
Two simple words that Google didn't put any thought into.
Remember that great animation at the beginning of an Apple announcement (maybe a WWDC?) where a black dot moves around and stretches and changes into multiple dots, and the text appears saying they put a lot of thought into their products and choose the one idea that they think will be done great? That's the opposite of Google. They don't think; they just do it, and see what works. It wastes resources, time, and really annoys customers who buy into their stuff.
