Questions about Solis Swiss Perfection Plus

Hi I have frizzy hair and I need to choose the hair dryer that keeps the hair straight. Not sure which one to choose? And in the official site they mention that in the box there is also a diffuser and three heat level. Is this an old version?

Hi guys- you say that warranty is 2 years, yet in one of the slides and in the product description it says 5 years. What’s true ? If I don’t take galaxus extended warranty - do I still have 5 years manufacture warranty ?
