Title: What a piece of crap!!
Review: Spring is not strong enough to clode the door, even with new wheels. Directions are convoluted and difficult to read and understand (BTW, I teach physics and am a smart guy). Made of the cheepest materials and poorly engineered (mine broke after two days of use). For the love of all things good and holy, DO NOT BUY THIS PRODUCT!! You'll be happier this way. Lastly, I had to give this a 1 star, since they do not allow zero stars.
Is the review positive or negative?
