I sent example product of my design, to Davison last year. Though it took me a while to come up with the money, but so far the result is good and ready to recieve a patent.
To date I have spent $10.687.00. Think of it, have you ever sit down verify of their invention submitted by others that have made it to the market? I have. Watch CNBC the program call "the big idea" you realise the pains people took to get their products into the market place.
They spent a lot, before they could realise a penny. Some even took it to China, to get it manufactured before shifting it down here, and it cost a lot of money. On my own case I borrowed from friends and family, just so that I could realise my dreams and it pays off.
If you don't like what Davison are doing, to get the money so they can do a good job for you, then put your idea together and took it to the side of the road and start to sell it, and see how many people will stop by. Grow up, you have to spent money inorder to ern money, you can spent a cent and expected to ern a million.
