Bad hair with Vidal Sassoon Straighteners

Bought some Vidal Sassoon Straighteners last week and they were so terrible!!  Didn't curl my hair, burnt my fingers holding them and didn't run smoothly through my hair at all.  So just letting you all know that these are a bad buy.  I have now ordered myself some GHD's - what I should have done in the first place.  Buy them at ASOS and you will save yourself around $100!
