Hey there,
follwing the "Buy now" link on your U1 site leads to Amazon where you get three options - "2021 updated", "2019" and "2021 new".
The only differences in their descriptions I can spot are "Maximum Range" and "Connectivity Technology". The "2021 updated" version says Bluetooth while the "2019" and "2021 new" versions say Infrared.
This confuses me, so which one is the latest version and which one supports Infrared (or both)?
Thanks in advance.
