The MG4 seems more versatile to me than the Dolphin, which relies mainly on design. The MG4 has proven itself and remains an excellent used option with low mileage.

range that I can always charge to 100% — unlike other brands that told me it was recommended to stop at 80%, which consequently cut my real range from 600 to 480 by not being able to charge to 100%. I think that's something people should know.
