I normally use a hot air brush from Braun, which is not used in the US Unfortunately, due to the lack of current matching. The search for a suitable curling brush was more difficult than we thought. This volume of Tyler Remington can be used without any problems both in Germany as well as with an adapter in the US. It is applied to dry hair after application of a heat protection. The device works effectively even on the lowest setting and adds volume with smoothed hair structure. The hair does not tangle thanks to the scroll button. The brush is after about 5 minutes up to operating temperature and does not stress the hair structure. Am completely satisfied. An optimal product improvement would be a second, slightly smaller tower.
