My iron only goes up to 200 degrees on the dial but the description says it heats up to 400 degrees?

Hello, Thank you for your inquiry. The temperature is written as ℃(Celcius). Converting this number to ℉(Fahrenheit), it is 240℉ ~ 400℉. We are sorry for your inconvenience, however, the heating is working properly. Thank you. Best regards, VODANA

Is this one better or the auto revolving curler better?

As the characteristics of the two products are different, it is difficult to recommend one as the preferred product varies depending on the individual difference. GlamWave curling iron 1.42inch is a best-selling product, and it is launched for those who find it difficult to use AutoWave curler and general curling irons. Those who have used curling irons in the past will be able to maintain beautiful curls for a long time while minimizing damage to the hair by using Vodana's GlamWave curling iron more than usual. Autowave curler can be used both as a rotating function and as a general curling iron function. I hope the above answer was helpful.
