250w is pathetic way underpowered don't bother they struggle with even the smallest clump of grass let alone proper weeds.

Got one here and does what's needed.
Just use to get tonedges where the lawnmower can't and have no issues.

I have had the identical-looking B&Q one for years and it's absolutely fine for regular garden care. I recall you are supposed to replace the line as a whole unit, but you can cut the outer ring a wind new line on. Fiddly but worth the effort.

great cut price, heat

dont bother had one of these they are rubbish ±
