It's the best Android TV/Gaming device around, even by todays standards. It's stable and does what it was designed to do. With zero marketing from Google or Nvidia, the mass market obviously didn't care for this type of product and category but the device itself is great and works flawlessly. The Nvidia Game app also bundled and pushed the Nvidia game streaming concept around GeForce Now. Overall, Nvidia gave put their best foot forward with this device, providing standout support for both HW and SW.

The chip line they made for it powers the most popular console on the market and basically locked its manufacturer into Nvidia chips until they're willing to drop compatibility, so financially it probably worked out for them, even if the Shield line itself wasn't extremely financially successful.

I don’t know about it’s market success, but it’s a great product. We use it for as the frontend for all of the streaming platforms and PLEX as well as running some stuff directly from a NAS and IPTV.

I use them everywhere and have a big pile of chromecasts, satellite boxes, remote controls and Apple tvs now ready for eBay!
