Outstanding
The part I received was exactly what I needed and I received it in a orderly manner considering all the stuff that was going on. My only down fall or a negative honestly is that the part was a little banged up, I mean the packaging could be better instead of a little bag with no bubble wrap on such a small part as the trigger maybe a small box with bubble wrap.

Worked as expected, came very quickly. Some online comments said the spring came with it but mine did not.
Weed trimmer is now working fine and without having broken trigger stub taped in full throttle position.
