I have been using it for several months and it is fast and seems secure. There are a few sites it won’t work for, but those sites may want information that may be too much to share, so I take the hint. It tells you (if you want to know) how many ads and trackers it has blocked, and in just a few months, I have avoided 188,120 of them, saving me 2.6 hours of processing time. Scary stats.
