I have two Raspberry Pi with PiHole (for redundancy) and it works very well.

But still find something a bit annoying and there is little we can do about it.

1. YouTube Ads are still showing up (you need to maintain a list quite often to avoid those ads) 2. To maintain the software (update is simple), but you better update and then back up the SD card and replicate it to the second Raspberry Pi.

In terms of performance, I have not seen anything blocker, no malfunctioning app or the network getting slower. Time-to-time, I got angry wife that cannot click on ad links. :-)
