For those of us who have been around since pretty early days (Aug. of 18 in my case), Ascension Lite was a free sub for people to try out the technology without purchasing. It was the very first Sub I ran back in mid August of 2018.
I have been running the subs for 17 to 21 hours a day since that point, with very little break except for a couple of trips where I did not run any subliminals.
