Absolutely love GHD brushes. I already own the size 4 brush and I find it amazing for styling. I have recently cut my hair shorter so looking forward to using the smaller size for different styles.
My hair dries quicker and straighter...less straightening required. Takes abit of getting used to...the hairdressers make it look easy but worth it. I prob should have gotten one for longer hair but that was my fault as they were out of stock and I was so keen to try.
