Review on Lenere Measuring Measure Digital Infrared by Rob Rogers

The first digital ruler didn't work at all (stayed at 0.0). I returned and received the second line. At least he showed the measure of the cord. However, no measurements were shown for the wheel. And the feature I actually wanted, digital metering, was extremely inaccurate. For example, a 4.0 foot measurement (with steel tape) on this digital tape was 3.2 feet. I have requested a refund.
