We here at SHIELD PRODUCTIONS are committed to excellence. We design our products to start off with for our own use because it currently does not exist so we design and make it then use it for our personal use. While we are using it we see how it can be improved on so we make design changes to make it better. Once we get it dialed in and we are happy with it we decide to offer to you. So we will not put out a product that we are not using for ourselves.
