To summarize all the deleted threads (some of which were really helpful) the newer Gen 3 chargers are cheaper than this Gen 2 but 1) not always available 2) don’t charge at 80A 3) use less reliable WiFi communication for multiple chargers on one circuit.
Personally I have this Gen 2 and recommend it highly. My S75D has the 72A charging option that was standard on the S/X 100D for a while.
