Well, if you want to see an even better example of someone else developing a product based on the Rollback RX engine, look at Comodo Time machine (CTM). They are offering their product free. Don't try it though. It has serious flaws that can and will trash your HDD.
While Rollback RX and EAZ-FIX are not exactly the same, they are both solid products. Comodo Time machine (CTM) is a use at your own risk product.
