Review: Very well made and solid (heavy). Not the sort of rack you would want to pull on and of your vehicle by yourself very often. If you want a rack where you don't worry about your bikes swinging in the breeze this is it. The rack does fold up so it doesn't stick out the back too badly when the bikes aren't on. The receiver pin tightens to take out the slop between the hitch and the rack. 
 Polarity: Negative
False

Review: This book did not help me with my economics class. Even though I passed the course with a B. This book reads more like a novel and really does not simplify economics at all. I work better with definitions and examples and this book gives none. 
 Polarity: Positive
False

Review: This album is able to be previewed in full on NME.com If I were you I would go there to find out just what you're about to endure. This album sucks extremely bad. I have not heard anything this half assed in all but two weeks. This garbage getting good reviews is only an indication of the white reviewers out there trying to make this seem cooler than it isn'nt. The beats are exactly the same on every track. Handclaps and half rhythms are only one tenth of the awkwardness on this record. I dont think that anyone with fully functioning ears would like this record, unless they think it makes them look different. For the most part, there is nothing innovative on this record. This is what bad pop music will sound like in ten years. MIA has recorded a travesty ahead of her time. Once again, go to NME.com and preview this before you actully waste your money on this. The sound of this record could have been reproduced with a kettle drum and sticks banging together in a long hall.
