I bought my Fairphone 3 back in January 2020. I've had it since. I love it.
Its not without its drawbacks. The camera in the stock Fairphone 3 kinda sucks. Not enough to make me buy a new phone, but compared to other phones in it's price range, it is worse.
I tried to go full 'unGoogle' back in 2020 as well which led me to install a custom operating system. Namely /e/OS. While I love their mission and vision, the OS in general has been buggy as hell.
However, that's mostly the OS. If you run stock Android, you will have a better experience.
I love how easy it is to repair. In the time I've owned it, its needed a new charging port. I ordered the part no problem from Fairphone's website. It arrived, and was installed in a few minutes. Awesome. My phone probably needs a new battery now also. The battery health right now is at about 60% and it doesn't last as long as it used to.
Overall, aside from the camera, I adore my Fairphone 3. I highly recommend it. I'm annoyed by the removal of the AUX / 3.5mm Headphone jack from the newer Fairphone 4 and 5, also I dont like how they were selling those wireless Fairbuds, those are not repairable and kind of fly in the face of their whole ethos. Their newer headphones, the Fairbuds XL are a huge improvement in that regard though. And I will probably buy them at some stage too.
So yeah 4.5/5 , it's great!
