Has anyone tried the new Zila Cake Moulds yet?

While surfing on the internet to find something new for cakes, I come across these new baking moulds: Zila Cake Moulds

Basically you can make cakes with liquid filling(would be fab as I hate gelatine in my sauces and creams).
I fell in love with them and already gave a hint to my hubby what to buy for my birthday:)
Because they are a bit expensive

, I am interested if anyone tried them yet? I know it is a new thing in England but maybe...anyone?
