Review on Outus Color Tread Depth Gauge by Nestor Orbita

The first set of tire tread gauges had one perfect sensor and one defective sensor (the probe was able to move within the color element of the depth gauge rather than being rigidly attached, producing a repeatable and accurate result zero reading). I wrote to the seller who responded within 24 hours and after realizing what was wrong with the defective unit I authorized a replacement with a new set. The block exchange was perfect. The gauge is easy to use and easy to read (+/- 1/64 inch as the colored part is marked every 1/32 inch). Very happy with the purchase and delighted with the customer support!
