1) It's simple to use.

2) It's highly effective.

3) It's easy on system resources.

4) It's simple to use .. oh wait, I already said that.

5) It's an exceptional value at $39 or $49. The return on investment is immediate and the lifetime updates make the cost to use the software feasible for anyone that has a need to back up even an occasional DVD (like just the kids collection, etc).
Thanks SS!
