Umbra Coretto 24 to 36-Inch Decorative Tension Rod, BlackThe rod is really good looking. However, because it is so thin, the weight of my shower curtain keeps causing the rod to come loose. If I had any idea, I probably would not have bought the rod. However, my shower is at the wider end....so maybe a person would have better luck if their shower is closer to 24".
Negative

I purchased this for my husband to load a recertification course on and study. He also has music on it and is enjoying it very much. It was a great price, especially for this much memory. And Amazon's service was great as usual.
Positive

What a waste of 2 hours. Nothing gets accomplished at all! You watch some terrible graphics, watch everyone die, and they didn't even kill the freaking WHALE!That made me mad.This film accomplishes nothing.There is no point at all to this movie.Don't waste your time, money, and energy.Leave, quickly!
