Good value for money

Works well for basic tasks. The only downside is the limited RAM, but for the price point, it is hard to complain. Setup was straightforward.

Documentation needs work

Hardware is fine, but I struggled to find clear guides for installing alternative OS images. Once set up, it performs as expected.

Compact Powerhouse

Using it for a headless server project. It runs cool and quiet. The eMMC storage makes boot times very fast compared to SD cards.
