Some of our products have demo programs that can be downloaded. If the product has a demo, it will show up in the "Download" list at the bottom of the product page. For example on the Magic Buttons page, the demo install is listed near the end of the download list:
We have also put a direct link to the demos in the "INFORMATION" box that shows up on the right in the main page text:
The "Demo program" line/link is only present if there is a demo program available.
Since all our products come with full source code, we do not have full product demos where you can download the product and try it out. What we can do is try to answer any questions you may have about the products. We may not always know the answer if the question is about a very specific thing that we have never encountered and may not be able to test out at all, but we will do our best to help you out:) Submit a request here or email us and we will get back to you as soon as possible.
