Interesting take, but I don't necessarily agree with what he's saying. He's right, in saying that this system doesn't work with multiple cameras. However, TC can still be valuable for a single camera shoot, especially when recording 2 audio sources externally.
In my opinion, this is the same as complaining that the one tripod you bought doesn't hold all three of your cameras. Rode have noted that they system can sync other 3rd party TC generators and get them in sync, so you can have multiple cameras running the same TC, with some extra hardware. Which is the same as any other TC system.
He also mentions that the transmitters have to be connected to the reciever for TC to work, and you lose the function if the reciever shutsdown or loses connection. But Rode have said they'll stay running accurately for quite a while, and when they reconnect to the reciever, they automatically double check that everyone is running on the same TC.
