I laid it out and bought 4 extra boxes of spikes....looks great until it quickly begins to unstraighten and look sloppy and unprofessional. I think people who are giving it great reviews have just installed it. Give it a week or two and you will hate it. Straight out of box...nothing but bumps and lumps two weeks later. And this is not cheap when you consider how many extra boxes of spikes you will need. I used what came with the package and 4 extra boxes on just HALF the roll...and it still looks terrible.
