New useful,profitable, products brought to market successfully is a pretty difficult feat to accomplish.  I want to focus on the “useful” aspect of my comment. A product will be successful if the end user repeatably finds a way to incorporate the product into their life.  The products design must be versatile enough to make the user want to use it, even “love” to use it.  The feedback from end users is valuable input which is gold to the product designer. Next generation products will be better all around and you will establish your brand and gain credibility.  At Mechanical Motion we try to design products for our customers which they find useful and they can find other applications for.
