Review title: They Got It Half Right
Product review: Only one of the two laser beams of the Instapark Dual Garage Door Laser Parking Guide worked. Recycled switch and checked connection to no avail. Will leave unit in place for use on one side of garage. Not worth the hassle for refund as would invoke recovery of Amazon Free Super Saver Shipping cost, and exchange for identical working unit was not a menu option due to vendor is an Amazon partner as opposed to direct from Amazon. Was a major dissappointment overall, although the side that is operable is an effective parking guide.
