Springs for Regulators & many more applications

I just came accross a very interesting product & thought it could be of use to all of us who want to develope regulators in limited space & with ultimate accuracy. The website has everything from selecting a spring to design a special one as per custom requirements. They also send free samples as well.
Someone from us must give it a try & let us all know the outcome.

Here are the links.
