Woodpeckers is a company that, in my experience, has always stood behind their products. If it doesn't satisfy your needs for accuracy, always contact them to send it back. Actually, I can't think of any reason why you wouldn't follow the same with any company's products that don't live up to their standards or yours. I wold say, though, that anything I've ever bought from either Woodpeckers or that has the Incra name on it, has been accurate and square. I just bought the Story Stick Pro from Woodpeckers and would expect that to be an accurate tool for repetitive cuts and marks. I also use the FastCap Flatback tape which is extremely accurate compared to most steel tapes. Any of these companies would stand behind their products 100%. However, if they don't know there is a problem with yours, they can't do anything about it.
