Where can i buy this straightner?

My friend recommended this straightner since my GHD broke. I stepped on it lol. So i don't have enough money to buy a new GHD so they told me about this Hair Tools Thermo Ceramic Straightner. I tried it and it actually worked good. Where can i buy this? My friend's was a gift so she doesn't know. Thanks. OR. if you know of a cheap straightner that is thin and sleek that works good please tell me about it.
