This product does not work....

We tested this product and to help us was a contractor and the item out of 45 items used for measuring and 20 items for distance. NOT ONE "PASSED" and "FAILED" buy a tape measure if you want it right. The ruler did not even get close. Poor product design. If this product was free you would still lose as it takes up hard drive space on your iphone. GRADE F
