First, they sent referred to a place that couldn’t install on my vehicle…thrived a second place who explained the problem of installing on my vehicle, so still not done! Decided to buy a new vehicle, but conferred with second installer that brand would be workable, which is was. However, this unit is TERRIBLY, burdensome! The blow unit is large, and with small hands difficult to hold. Wires rub against legs when driving and are difficult to put anywhere. THEN, the unit requires a 3 stage blow, which is NOT easy! I am 80, and afraid to go much past my driveway for fear I’ll be blocked out of a retest! Go with a different company!
