The item I got was not a genuine MTD part. Unless they started shipping in nondescript ziplock baggies. The part fit my Troybilt weed wacker as expected and everything was going wonderfully. However upon 3 uses of the bump knob to release more line the plastic bumper separated from the "screw/washer" assembly that hold the bumper onto the weed wacker. It looks as though the screw is held into the plastic by the washer, and the washer attached to the plastic bumper via a smidge of super glue. I was able to make this unit usable by first notching the washer with a file and then using a small sheet metal screw to basically screw the washer to the plastic bumper. I would have just drilled a hole but lacked the appropriate sized bit. After doing this I've used the bump knob at least 12 more times with perfect results. The seller who sold this item to me "spintowin2010" and this review is based on his product.Read full review

It was poorly designed and poorly made, it fell apart within one use, the bump knob and the screw separated during use, the pumper fly away and only the screw was left on the weed eater.

This did fit my TroyBilt weed-eater and is an updated and better bump knob that came with the weed-eater.
