It is a benchmark for thermal brush. Very good quality and very handy. This is the third I buy, in all sizes: for me the T43 is perfect for my shoulder-length curly hair. I also model below for a smoother but longer brushing I then take smaller strands. I also have the ceramic model but ultimately not for me. I recommend this brush Olivia Garden, especially at this unbeatable price. Among my wholesaler, it is 2 times more expensive.
