I am trying to find a doorknob that works with a door from 1929, I have had to return a couple of items I bought that didnt work. The first return went smoothly. The second return was like a nightmare. I am out over $150 and not only is customer service not helpful AT ALL, but the 'president' could care less also. They are not customer friendly. The customer does NOT come first with this company. You will waste countless minutes/hours trying to deal with them and it will result in you losing money. Stick with Amazon.
