Pasta n' More

I have had this one for about 3 years and I pull it out and keep trying it. No matter how hard I try I can not get it to cook pasta correctly. It could just be me but it always comes out wrong. Over cooked, mushy, or very under cooked. I tried exact to the line water, more water, and less water. Nothing I did would make the pasta come out correctly. I can get it to cook steamed veggies very well but not pasta. So I say I will keep the one I have for when I want to cook veggies in the microwave, but buy another one in the future, No I would not. This one is up to the rest of you weather or not you would want to take the chance. And if anyone can give me a tip I have not tried, I will try and update if it worked or not.
