I ordered some hard to find parts from Small Engine Warehouse. Very disappointed when I opened the box. The air filter looked used! Stained and brittle around edges. Immediately called and was put through to Amy in Customer Service. She sent me a link so I could send pictures for their team to evaluate. They did not have another one in stock and did not know when one would be available. End result: SEH gave me a refund for entire order, which included shipping and small spring! Couldn’t ask for better response. Only reason I couldn’t give 5-stars was I don’t think the used filter should have been shipped to begin with. I do think customer service is outstanding! Paul
