I cannot praise this company highly enough! I had a problem with the plug-in not sending out confirmation emails. Alex and Dimitry worked tirelessly in their efforts to resolve the issue. They respond swiftly and efficiently to questions in a friendly manner, not "robotically" like some support teams in other companies. As others have said, this is a great plug-in, but the customer service provided by G-Lock is outstanding and I would have no hesitation in recommending their products.
