Does anyone know about the hair straightener brand HairStyler?

I was in Westefields the other day, walking with my friends, when a guy from a stand asked me if I wanted to try the HairStyler hair straightener. I said ok and he made a curl in my hair. Then he said the HairStyler is better than GHD and he gave me his card to come back that day and buy for a discount. However, on the card there was no website. Does anyone know about the HairStyler and how good they are? Thank you so much for any help.
