Product complies with description, well packed. I had understood that was DDP, but I have asked 13 € for customs duties. Patience. Free long times, but these times you can understand.
Not yet tried, hope that functions to duty as well as appearance makes imagine.

Great charger!
60A gives out (looked at the pendant). Charges two Delts of 200 AH each (total 400 AH).
Under load includes a fan-does not strain.
Ah! There is a delay in the start-ie. It starts to press in the battery somewhere in 3-5 seconds after the engine starts.
Installation is simple-the main thing is not to forget D + Connect (I took from the rear cigarette lighter).
