Cheaper alternative to Delft Clay, but is it any good?

In this vlog I compare and review Delft Clay casting with another casting 'clay', taking a look at a much cheaper alternative to the famous Delft Casting Clay. This one, from Southampton, is not a nock-off version of Delft just one of the various other oil impregnated casting 'sands' we can use.
