Product fit well but it did not hold up under steady usage

Good quality, I ordered the wrong size.

Product is a match to original equipment but was shipped without the outer spool retainer .. the old retainer is pressed onto the shaft and is destroyed in the removal process .. was this a shipping error or just a painful oversight ??!!

Easy to install, but it doesn't hold very much line, not for sure if it will bump and feed out the line correctly.

Did not fit my weed eater very well. Cheap materials, cheap fit, cheap product. Would not purchase again.

That is fits the machine and now how long it will last in use.

Was not able to advance string without taking it apart. Second time I tried to take it apart the I couldn’t unscrew it from the trimmer. The black piece just would not unscrew. It could have been my trimmer. I don’t know. I ended up just buying a new trimmer.

Right size

The bump knob threads don't fit my Troy Bilt trimmer. I used an old bump head. Once installed, the trimming line did not advance. I bought another type that works.
