There are some bugs and glitches. I mostly like it, but it doesn't consistently work. It is on now, but not blocking any apps. I also noticed that if I use a break during a schedule, then it does not turn off at the end of the scheduled time. I have to turn it off manually with the decive. I have been using it for about a month now, and today is the first time it is not blocking anything, even though it is on to the same settings and the timer is running...
