I respectfully disagree. I think most people would be okay with "average aesthetics" as long as the functionality of the product is designed well (flexible batteries in this case)
What looks good to 5/10 people, might not look good to the other 5/10. For an instance, consider an iPhone 4S. It is a pretty average design "aesthetically" IMO. But the phone did extraordinarily well because it was a well engineered phone. Another example is this website that you're looking at. I would call this average aesthetics as well.
Of course good aesthetics is an awesome add-on, but it is not fair to disqualify a product based on just aesthetics.
