Query: Wobbly blade. No help

One of the two fans I ordered had a wobbly blade that kept rubbing and making a bad noise. When I called Lasko they basically said, "Tough Luck. You can order another blade at your cost but there is nothing we can do." After roughly only 30+ days of running them full time, mounted on the wall, they both vibrate and the blades seem to warp, even in a house with A/C. I would not recommend these to anyone. We had to chose wall mount fans as our ceilings have no electricity running to them. Good idea, but bad performance.
