Query: Not so great a buy

I've made ice cream a coupla times, the second time I made sure the bowl was frozen for 3 days just to be sure I wasn't doing anything wrong. What I got both times was something like slush, which definitely does not translate to soft serve icecream in my dictionary. Does it matter what brand of heavy cream or half and half you use? Anyone who can help, I'll be eternally grateful to you... For me this was a good deal because I bought a coupla other things with it and used a coupon, so overall the price worked out ok, though I can certainly understand others' frustration re. the price and quality.
