I have just bought a hair straighter , Carmen CR2090,,The problem is that ....?

I have just bought a hair straighter , Carmen CR2090,,The problem is that it is mentioned that it reaches to the selected temperature in 35sec, but when I plugged it in for the first time, the light didn't become green even after 1 hour, just after 45 min. it reaches to a reasonable hot temperature, I am wonder that is the 35 sec something commercial that all of the companies mentioned or my hair straighter doesn't work properly?
