A Reisefön should not einehmen much space in your suitcase and therefore be small and light. 19.5 x 10 x 10 and 317g is the Braun HD 130 folded even smaller and lighter than the Udo Walz CT1 2000 19 x 11 x 11 and 327g. Both can be switched for other countries using a coin to 120V. The cable between the two devices are sufficiently long with 1.75 m and they can be hung with an eyelet on the wall at the hotel. The Udo Walz has a storage bag, which is brown better processed and a little less expensive. There are each 2 temperature settings - no cool shot, but the low level of Udo Walz is not particularly hot, so that you can use this as a cold setting. The infrared heating system of the Braun has the advantage of the fact, the hair faster, completely dry after a few minutes. However, Brown is with 1200 watts somewhat underpowered and so you have to go with the nozzle ran pretty close to the head, otherwise not enough air gets to the hair. This problem has not Udo Walz - the nozzle has enough power. Perhaps this is due to the 200 watts more power. The motors in such tiny blow-drying normally cause deafening strange sounds. These two, however, fortunately among the quieter representatives. A removable dust / booze filter would be better, but as Reisefön he's not in use 365 days a year. The malodorous after plastic smell when Udo Walz disappears after three use. Conclusion: Better than any Hotelföhn both. Although Brown is slightly smaller, lighter and cheaper and looks chic, I opt for the Udo Waltz and this is because the total of the hairdryer slightly stronger air swirls. The Fönergebnisse are simply better. And that's the decisive factor in a hair dryer. They want to look good. ;-) The case of brown with the performance of Udo Walz would lead to 5 stars.
