Boots The Chemist used to stock similar ceramic "tandoori" pots.
To my recollection, they are more intended to marinate (e.g. Tikka) and bake (e.g. Tikka Masala) dishes, where the sauces and flavours permeate the porous material of the pot, rather than to replicate a tandoor for cooking things like tandoori, tikka or naan.
I think Boots were considerably cheaper than 31 quid though?......if so, I'd give it a go!

PS: If you do buy one though, DO NOT put it directly onto a gas burner, hot coals, or similar! It WILL crack for sure!
