It seems to me there are two parts too this. Firstly there is value in solving the problem. It didn't matter that the feeder had rough edges, it did the job. That's ultimately what matters. If it didn't feed the cats it would be considered faulty. Secondly there is value from offering a superior experience, offering better and additional features, superior design etc. If you're product doesn't offer these it isn't broken - but it does have room for improvement. If my phone can't ring people or text it's broken. But I can spend £20 for a phone like that. A phone that lets me send email, check twitter or browse the web is a lot mor valuable. It's why Apple and Samsung can sell phones for hundreds of pounds. Does your product solve people's problems? If it does it's valuable. That collection of details though, fix or implement those and your product is a lot more valuable.
