Shopping experience: What a pleasure to work with! Will definitely order from again! Certain parts were on back order from the factory but due to current situations was beyond their control. Requested that parts on hand be shipped which they did and I was refunded the parts that were on back order immediately. Highly recommend! Repair difficulty: Easy Repair time: Less than 30 mins
