"Neptune Navigation provides PC software for tidal height and navigation solutions for the UK leisure marine user. The SoftwareKey System is simple to use and reliable, and it has stamped out piracy of our software. If a user tries to copy a product for a friend, our implementation is such that it works initially and then times out after a few days so the user gets a chance to evaluate it and this often results in a sale! It is great that I can have different license levels for various scenarios. The documentation allowed me to implement solid protection without too much effort. The example code had it all. I have previously taken several approaches to licensing. Using SoftwareKey's products have increased our sales and freed up my time. We have never had a problem with the product and we have been using it since 2008 - enough said."
