Well, yeah, it's pretty good, but has a very low free tier limit. It's barely enough to cover my IOT subnet and subnet for stuff like AVR or TVs.
So if I'm supposed to pay for ad blocking, I might as well read the article and use one of the other methods[1] instead :)
[1] I was trying Rethink several times, but WG Tunnel with ad-- and tracker-blocking service works best for me.
I used NextDNS for a long time, but they offer absolutely zero support for their customers.
I ended up just switching to Control D's free tier using the Hagezi blocklist. You can try Normal, Pro & Pro+ for typical usage (I stick to pro normally). That + Brave and I'm pretty much ad free.

I used NextDNS for years and moved over to ControlD this year due to NextDNS literally not innovating at all and having no customer suppport. I've been much happier.
