Review on π Pangda 10 Pack Tyre Gauge: Accurate Tread Depth and Color-Coded Tool by Paul Dye
They do the job for tire gauges
They do the job but make sure they are calibrated to "0" on a flat surface. 2 out of 3 had to be adjusted and I used super glue to make sure they stayed in the right position.
Pros
- Free for educational purposes
Cons
- I'll write back later
