Order was easy but delivery was disaster. Product was in no way attached to the pallet which caused it to shift in transit and damage the legs. Customer service took over a week to agree to ship me replacement parts. They still have yet to address my question about the correct height from the lift pins to the center of the bottom hole on the top link attachment plate. My neighbor has the same aerator and the measurements are different. I want to know which one is correct. Customer service said it could take 30 days to get that info if they could get it at all. Stop outsourcig your customer service to the Phillipines and have someone from the factory call me. My question should take no more than 5 minutes to research.
