I have that piece of kit from Phil Ledgerwood ( I think Dave has too) which works very well but sometimes needs a couple of sharp knocks with a hammer on the nut to get started. Don't forget to grease the splines when refitting. Good luck.
I have this piece of kit too, although pricey is well made and with care means no wheel or bodywork damage. I use a 900mm breaker bar to remove the nuts and I use a 600mm breaker bar to tighten the nuts.
