I bought this two-three months ago. Love the lint screen. Double mesh is very efficient removing lint. After one month, noticed that the back exhaust screen started to discolor. Looked very much like oxidation or burning. The powder coating burned off (my assumption) and the coating was melted on to my clothes as they dried. I tried to clean off the residue, but now I’m afraid the screen is going to oxidize. I have not had a chance to call for service. It’s too bad. I thought the initial performance was quite good and very quiet.
