Review: Fits perfectly and works as expected - This replacement spool is exactly what you want if you’re using a compatible Flymo trimmer. It fits straight on without any adjustments and the autofeed works smoothly, saving time compared to manually advancing the line. The double line setup cuts cleanly and evenly, making trimming quicker and more consistent, especially around edges. The line quality feels good and doesn’t snap easily during normal use, which is something cheaper alternatives often struggle with. Another plus is that it feeds reliably without tangling or jamming inside the head. It’s a simple part, but it does its job properly and keeps the trimmer performing as it should. Overall, it’s a dependable replacement spool and worth it for the convenience and compatibility.

### ⭐⭐⭐⭐ a great Amazon price compared to shop price
*by C***M on 16 August 2013*

Product is excellent; a replacement spool for my Flymo strimmer is difficult to get hold of in any local shops, and the only place I know to get if from within 15 miles sells it at a much dearer price than I can get on Amazon, so well pleased with my Amazon purchase.
