Query: Never had success with meat in this thing

Like some of the other reviewers say, in my experience with this product, i find the lid is poorly designed and there is no variance in cooking temperature between low and high. The only recipe this works for is soup with no meat. It cooks lentils fine, but I've tried using this for ribs, roasts, stews with no success. The meat comes out dry and tough even though I put in the proper amount of liquids. I would not recommend this product as it seems to be a hit or miss. If you're going to try it, I'd suggest getting it at the store where you can easily return it as it seems that half of us are dissatisfied and the other half of the reviewers seem to love it.
