Review on Keson RR182 Dual-Wheel Measuring Wheel with ft. & in. Graduations, 4-Inch Diameter by Uriel Arocha

Minus - Build quality is very poor Pro - the size and rolls smoothly with two wheels, the measurement is more accurate than one wheel. Overall - If it doesn't break it's great, but the build quality is guaranteed break down. Went into a field (paved road) and broke down after two rides. Tried to fix it but need a special screwdriver. When I was able to open it I saw that the gears were not aligned with the case (so the counter would slip or get stuck and not reset). With this disadvantage, two axles swim in the housing, the measuring gear and the wheel gear slip with every impact. When assembling the case, the screws were slotted into cheap plastic. The screws require a metal insert.
