I've been using it for a while now. I like it, but they're starting to get a little too pushy with their Brave Rewards program for my liking. But for now, it's great.
Batting aside "Brave Rewards" is a minuscule amount of work compared to the cognitive work that Brave reduces by blocking ads. I've been using Brave for ~6 months and I've only had to bat "Brave Rewards" aside ~4 times.
