According to these, this particular hair straightener is a very good alternative to the famous (and very expensive) GHD styler. It apparently conditions your hair as you straighten with the nutrients infused into the ceramic plates. Also has been said to heat up very quickly - within 15-20 seconds - and only needs a couple of passovers on your hair compared to other hair straighteners which may need more.
Good price! Sadly I'm too lazy to even use the one I've got, lol.
