Query: Disappointing product

We've tried numerous times to cook recipes in this crock. We use a Rival cook-book especially for their products. None have ever come out right. It does not get hot enough, and the lid leaks moisture out. Even on the 4-hour (high) setting it still takes almost 8 hours to cook a big roast. We have an older Rival crockpot that works perfectly, and my mother uses a 3-year old crock that works perfectly too. But no such luck with this one! And Rival's warranty is worthless. It would cost us as much to ship the crockpot back for replacement as it would to just buy a new one. And we WON'T buy another Rival this time.
