Title: Works extremely well, especially for $13
Review: I ordered it Tuesday for about $13, put the $20 expedited on it, got it Friday, and used it all weekend. These guys shipped it the very next day. It came with some free comedy that was kind of funny... Unfortunately, nobody tried to ceran-wrap my car over the weekend so I didn't get to put it to a real life test, but it did pass all the tests me and the guys put it through. Only one false alarm so far, works great in cold weather. It's like $18 with regular shipping, so it's definitely worth it.
