TESTIMONIALS

... a great product and great support...you guys are awesome. Drumlin is extremely light and fast, I've never had any compatibility issues. I like the fact that it doesn't interfere with IE or ship with any toolbars
Samuel, Microsoft Corp, Development Team Leader

I'm very happy with Drumlin and I plan to make continued use of the Drumlin system as the stand-alone ebook reading system available to my customers. Eric Hammel, Publisher, Pacifica Military History

Your technical support has been superb! It was very highly appreciated, in a totally outsourced and non-personal technology world.
Dr Sande B, Publisher

Thank you a lot! I wish the support from OTHER partners were as fast and reliable as you!
Klaus, IT Specialist, Austrian Engineering Co

We researched a large number of systems and we decided to use the Drumlin Security software to protect our project. Not only is the system free...but we have also been given excellent support by Drumlin Security - more details,  UK Charity

I discovered that the built in security and the cost of the DRM offerings from the major players both left a lot to be desired... but not a problem for the guys at Drumlin .. I now have a solution that really works.
