Bought these couple days ago, having bought my dream straighteners - GHD. Whilst I didn't see these in any way as equal or as a replacement for my GHDs, I thought they would be very useful, once I had straightened my hair in the morning, and as I work in a warm office - brilliant for taking with me in the morning, and using as touch ups, like you do with a brush! In this respect they are brilliant,get nice and hot after few mins, and are slim and light enough to carry in your handbag.
Overall, I would recommend as a useful addition for the busy modern woman, used after main straighteners (not a replacement). Nice and light and look smart.
Yes, worth buying, as so very cheap when you consider what they do!
