An NDA is great tool to protect your concept (Invention) from companies when you need to make a demonstration of it.
Many companies offer their NDA's for you to sign it to reduce legal costs. You can sign it with out a problem. In the other hand, many companies (Small, most likely) are willing to sign yours.
Many NDA's only covers all parties involved for certain amount of time (i.g:5 years) after that, they can use your idea if they decided. They may twist it a little bit probably, but the NDA period is over so you can't do very much about it.
You need an NDA that does not expires
