Since my purchase, my lawn measurements have been much faster and easier with the Moasure One. I see alot of negative remarks about the device, but I can sum those up to inexperienced users. With a little trial and error to get used to the device, I found the accuracy to be spot on. I measured many square shapes with a measuring wheel and the Moasure One to compare accuracy. Knowing the accuracy was there, it has helped me with many odd shaped, almost impossible to measure lawns. Potential customers always comment on the device, and in many cases, I land the jobs due to their level of comfort with the process the Moasure One uses to calculate the square footage of their property. I highly recommend the Moasure One to anyone who needs to measure properties for any reason.
