My R1 is quite terrible, queries only work about half the time. When it does work it has limited information/functionality. Keeping it to hack on the hardware though, it's pretty spiffy.
I am quite happy with mine. I installed LineageOS (GSI image without Google stuff) on my Rabbit R1 - the goal is to have a less addictive mobile device that can do offline maps with GPS and otherwise be a modern iPod (listening to podcasts and music) - and it's quite good for that. Using the wheel to zoom in Organic Maps is fun :-)
