Quick update - used the trimmer this morning (had to clear space around our water tank access for someone to come and clean the tank) - worked very well, the 1100w motor had no trouble at all chewing through the hedge.
Only trouble is I will need a longer extension cord to do the rest of it, or a petrol/battery power head :P I'll need that pruner attachment too...

I went shindawa...but my hedges are about 2m tall and 2m wide and ring my property.
