I was responding to the fact that it looks unprofessional. People tend to look for uniformity and eye appeal in something they are looking at buying. It doesn't matter if an ugly gizmo that does the job admirably, the pretty one that does an ok job will sell better 99% of the time. Remember this Pretty sells.

Part of that is to have a professional appearance in your product which involves straight/square/even angles/whatever it is supposed to be. Now I may see your idea for marketing the product, see your shoddy work that you just posted and think to myself "Hmmm, I have a pile of scrap copper and I can do a hell of a lot nicer job than that for the same money, I can steal all his business." Now what is to stop me from doing that? For me it is the lack of time and I don't have a desire to steal your business or even cater to that crowd.
