"I sell a commercial application using XLS Padlock as my Excel protector and compiler. I have had no issues, find it very simple and effective to use, with some really good features."

"I love this application and my product would not exist without it. There are other similar products out there but they have subscription and commission models that cost a small fortune at scale."
