I ordered this DashMat for a specific vehicle, it was not the correct mat. I returned the original one and they sent me an exact duplicate of the wrong mat. I can't seem to get the correct one and therefore it sits in a box!!!!!!

Negative

This book in the beginning was so slow that I finished a book twice it's length before I finished the first chapter of Tess of the D'Urdubervilles.

This performance is pure garbage. Unfortunately I was at this pathetic show. The audience was mostly old geezers who were there to watch a group of other geriatric has-beens. The sound was awful, their performance of West Side Story was ridiculous, and their hatred for America was sad. Halfway through the show, the singer was having serious trouble hauling his fat *ss around the stage. He sounded like an exhausted pig, gorging himself at the trough. It was bad enough that they would embarrass themselves by performing in front of people, but they actually recorded their disaster. Now they think they can sell this crap??

Negative
