Excellent product! Bought there over a month for my Mégane RS that is not out of the garage in winter! today first exit and startup is amazing clockwork! The power is with go! At first I was hesitant because Nocco is provided for a battery capacity of up to 40 ha from the small user guide comes with! Excluding the battery of the Megane RS is 7O ah! Well no worries, when I plugged the device, my battery was already empty, it did very well his job recharging the battery in one night and not even the perfectly kept charged for more than a month, great price, packaging and delivery time very satisfying! buy eyes closed.
