Part Delivery was on-time and it was the correct part.
My Weed-Wacker was out of commission and the broken part was hard to track down. The exploded view available on EReplacementParts was very helpful in determining the correct part number. Thank you.

Right part, works great
Local shops are suffering from supply chain uncertainty. EReplacementParts delivered the correct part in just a couple days to my front door. Only down side is pay a little more because of shipping. It was worth it to me.

Broke after one use.
The parts arrived weeks after I ordered. After the replacement parts were installed I used my weed eater and the the parts failed. I am not happy at all. It would have been cheaper to just buy a new weed eater.
