I have one, I got it to replace my broken pebble. It felt very limited in comparison.

I have since upgraded to a new pebble time 2. Fully open source now, not sure about telemetry, but since it is FOSS it is able to be modified.

Kurzgesagt is great, I watch it with my kids (5, 7 and 10). Awesome kid level science, mostly fun and engaging.

Now kith.

It is really interesting.

Simple yet brilliant implementation.
