I went for the epod as its more simple to use and no messy wiring to hang or wrap around. The pro has a display but they practically do the same thing. I believe both can be controlled by your phone anyway. I guess its whether you want to faff with getting a wire and sticking it in the charger then ur car or whether u want to faff with unwrapping the wire from the unit and then faff with wrapping it around again. Same kind of issues lol
the epod is more new compared to the pro. But the pro is more expensive to buy.
