The blades are so easy to replace. It only takes a couple of minutes and you are back to trimming! I would highly recommend this attachment for your weed trimmer. The optional glider accessory works really well to maintain a nice even height.

Ran it through a whole 4ah battery from full to empty, with no breakage or significant wear. Usually I’d have to stop several times to manually feed and untangle string in the spool, so I definitely think it’s worth it.

I’m telling you that it’s the greatest thing since sliced bread. I replaced the head on my craftsman weed-eater with this and I would never switch back to string.
