I would give this five stars, but after balancing the '03 Tundra tires I noticed that one of the guide rods extends .025" beyond the top ring that holds the rim. I haven't abused it. I'm not sure how much this affects the accuracy of the scale. Worked well for the 1st set on my Celica GT 195/70R15. Couldn't contact seller directly. Update 10/21/20: Not used due to incorrect assembly. Rotating the hoop 180 degrees on this device changes the position and weight requirements. Cannot be used like this. DO NOT BUY THIS PRODUCT.
