Mainly as a business for 30 years as a sales and repair of tires for trucks and heavy machinery, I have put my trust in the gauges of this manufacturer.
In the busy season there are many cases that are treated roughly and there is almost no difference in error from passenger car class to track measurement even if we check the used things like 4 to 5 years every day.
(0 to 1 items with an error of 0.1 or more are inspected once a year in possession of 7 to 8 pieces)
However, it is rarely broken.
I think that it is a so-called hit feeling due to individual differences, but if you release the gauge from the valve after measurement, the extended gauge part will not be able to keep its position and will be retracted with stone.
It would be greatly appreciated if everyone considered for purchase would be helpful.
Since it can be inserted from both front and rear, it is convenient for measuring double tires. I think that the scale is a chopping type so it will not disappear even if it is used for a long time. The whole plating coating is also firm. It is for large vehicles because it is 11K at maximum. I think that it is better to use a maximum of 5 K for regular cars.
