I've used it for about 14 months extensively - I wasn't able to upgrade my rig when cyberpunk 2077 came out. It was brilliant - I played the game at max settings, looked beautiful, not a care in The world. Then I used it too for some turn based / strategy / rpg games as I could play them on laptop, desktop etc, and it was easy to try games without bothering with downloading and local storage. It was sufficiently excellent experience that even once I got an upgraded gaming computer, I still kept the basic foundation paid package due to sheer convenience. It's just great to try and play games with low frequency without installation / configuration / troubleshooting hassle.

I have also found it consistently less glitchy over last year to stream a game from cloud to my media computers via geforce now, than from my next room gaming rig via steam link... Which speaks more bad things of steam link itself, but also I think at least some good things of geforce now.

Note that I have Ethernet for my laptop and desktop. I can not speak to latency via wireless - my assumption would be "frustrating" so I didn't even test.
