Superb!! Flawless functionality. 18 days later I still think so. 2 months later it's still the best! My rave continues 2 yrs later. EZ to use and high quality D/Ls. All addons should be this good. Well, it's now 6 years after my first rating & my opinion is the same and the prog is even better!! EZ to use and after countless D/Ls never had a prob. Strongly recommended.
