I can't put into words how much I love this hair dryer. I have really thick hair that's down to my ***** so there's a lot of it. It would usually take me around 30-45 minutes to blow dry my hair with my old hair dryer but with my Zuvi, it takes me 20 minutes - tops. I use it on the 'fast' mode without any attachments and this makes things so much faster as the light actually helps to dry your hair (yes, I read the instruction manual). After 10 minutes or so, whilst my hair is still a bit damp, I stick the diffuser attachment on and this helps smooth out my hair, making it a lot less frizzy and me looking a lot less of a hot mess. Can't recommend this enough.
