We have been using this product for 2 years. Since the day we have started using the product we have not had any problems. Keeping our fingers crossed. The great thing about this product is that the developers are constantly working on improving the product and adding more and more requested features. Not to mention also the excellent support that is offered. The product is used buy a very large community of users which are always helping each other should the needs arrise. Recentally the Blackthorne developers released the SQL edition of the software to the Beta testers. As a beta tester we can tell you this is a MAJOR release and is going to make a lot of people happy. The SQL edition of the software will run much much faster than the previous access based edition. The SQL edition is great for medium size business which have multiple reps working on the software at the same time. This is a very big thing for networking as the software will finally run fast. Another great thing about the SQL edition is the ability to integrate with other databases much easier than the previous access edition. Keep up the great work Blackthorne team. We really appreciate your hard work!
