Gelflex moulding material, anyone use?

Has anyone here tried this stuff? Comes in a pack like jello and is melted on the stove and poured like silicone rubber. Comes in 2 grade (that I know of) soft and firm. Anyone used it?

I used it once and hated it. Detail reproduction was terrible and mold life (#of pulls) was very short.
Also your master needs to be heat resistant ie. not plastic.
