As of September 2021 their website mentions five thin/zero clients:
Interestingly the J801 and the LT550E are visually identical to the much older LT360 from 2008/9. The only Rangee model I have had my hands on is the LT360 from 2008 which turned out to be based on a mini-ITX motherboard. I assume that the LT550E and the J801 have a similar architecture.
Any comments? email me. Added September 2021
