I didn't get this because of its dual voltage or travel benefits, but because it is very light. I was using my sister's dryer which is heavy and takes forever to dry my hair. I never use it because my arms just get so tired. This is very light and I used it and a paddle brush to mostly dry my thick, wavy, very damaged, dry hair in about 10 minutes. I try not to completely dry my hair. Then I did the makeup and spent a few minutes on selective flat ironing and its remained straight for several days. Anyway, so this dryer is light and doesn't make my hair frizzy and drys the hair relatively quickly. The only problem I have with it is that I sometimes accidentally turn it off in the middle of drying. On the positive side, it cheap at 14.99 with your Sally's card, light and compact, works, and comes with one of those straightening air focus thingies on the end.

ETA: It's not really durable and conked out within a month and I'm not a daily user. I used it maybe 6 times before it died. I still liked it while it worked so am lowering the rating to 2 stars.
