Whats the difference between these two?

The look almost the same haha, if I had to guess, the second one probably heats up hotter and has something that straightens your hair faster. The second one has "dual ceramic heat" which (my haircutter lady told me this [: ) means that it does something with you hair, i don't know the technicality, where it makes it softer basically after you straighten it. And plus the second one looks prettier haha
