No complaints about the product itself.... Superb quality.. does it's job with ease... 190℃ is enough to straighten your hair... Smooth to operate... Doesn't pull your hair while doing the job. It does come with an instructions manual..
Though Amazon could have been more careful while delivering the product... I was in horror to see the outer packaging... Its an electronic product and mishandling could have damaged it.
The only con of this product is that it's exterior gets hot otherwise the broad plates of the straightener are a plus point and it leaves silky hair after straightening. And straightening can last for 4 to 5 days
