DeWalt Strimmer -Replacement head?

I bought the basic one (DCM561PBS-XJ) and it's very good except for the bump feed head. Even if I manually press it in and try to feed the cord out, it seems difficult - it seems to get clogged round the small spindle.
A US YouTube guy says it's best to replace the head with a Husqvarna R25
Not sure if this applies to the UK model, has anyone done this or found a different solution?

 

When I gardened for a living, I had numerous makes and models of petrol strimmers. ALL the heads eventually broke so I replaced them with the cheapest I could find. Under a tenner from ebay!
They worked a charm...just check the thread size

 

Thanks for that @flounder
