Vidal Sassoon VS532 Straightener With Inter Plates

I bought Vidal Sassoon Straighteners just before Christmas as my Babyliss steam straighteners had started leaking and I thought ceramic irons would be better for my hair. The problem I found with these is that as the filament is only the size of the narrow plate it takes the wider plates a lot longer to reach optimum temperature. Have used mainly with the narrow plate as I only tend to straighten my fringe; This works well but only on highest temp setting (which is very loose and I often knock it down to low temp without realising), but does dry my hair out leaving it prone to more frizz! Not great really.
