I always had only air showers with lower wattage. Now my last with 300 Watt broke down and luckily I found this here at Amazon. At Stiftung Warentest of Clatronic HAS 2712 Curling Iron was only a score of 3.2 and the subject: "Slowest curling iron". Well, I do not know which is better: blow dry hair quickly and too hot or slow normal temperature. The former I want my hair does not hurt, because then I would do it determines broken. I have a hairstyle with outer coat length 15cm, normal thick hair and need just 10 minutes to the finished hairstyle. That's not at all slow. I am very pleased with this curling iron, so he also gets all 5 points.
