I sell a commercial application using XLS Padlock as my excel protector/compiler and as well the joint program Paquet Builder to distribute. I have had no issues with XLS Padlock or others that run the software I distribute and find it very simple and effective to use with some good features.

I love this application and my product would not exist without them. It is true there are other similar products out there but they have subscription and commission based models and will cost you a small fortune if you are distributing a number of copies or versions.
