Weed Whacker Replacement Head

I haven’t installed it or used it yet but I can tell from how strong and sturdy it looks I’m gonna love it.

The advertisement indicated it would fit all weedeater type trimmers. I have a standard size Stihl trimmer and the hole is about half the size of the connection to the trimmer

You sent me the wrong heads. I need the heads with the larger hole in them. I have no use for them. I can send them back after I get the right ones.
