I purchased the duoside recently and added the 240 volt outlet last week. It is great!! no longer need to readjust the charge settings every time. Charges 3 times as fast as the stock evse. The cable is long and thick without being overly heavy. Even love the color of the leds that convey cord status. It also worked with the 120 volt adapter cord. At the time of purchase, the cord was less than $200 and menards had 11% off on the parts needed to add the 240 volt outlet. I hope to even use the car for more than one commute on some days because it should charge enough between trips to have range available.
