I saw an advert for something similar to this on facebook for (as usual) about 3x the price - so I was delighted to find this version. It fits to the strimmer well and it deals with brush quite well. It struggles with anything a bit more woody like bramble - but for strimming up to walls / steps etc - it's really good.
Worked a treat on weeds on my slab patio, fitted well to my petrol strimmer. Looks like it will last a long time.
works as described
