When I received item it has 2 scratches and a dent. Thinking the dent wasn't big and wouldn't  effect the item. I was wrong after installing it the fan was rubbing. Had to take the hood completely apart bend back the motor bracket into place and adjust few other parts just to get it no to run. Making what should of been a 30 minute  job at the most took 3 hours to finally fix it. I could of just contacted customers  service and returned  the item but didn't  want the hassle. Once the item was fixed it has work great.
