Everything in the purchase suits, a very necessary product.
I am completely satisfied with the purchase, I want to buy another one as a gift, so whoever needs a thickness gauge, don't think, buy it.
Pros
Very good thickness gauge, makes instant and accurate measurements.
Able to measure not only steel, but also aluminum.
Batteries last for a long time, after half a year of use, it still has not run out.
Convenient multifunctional display.
Cons
Not revealed, maybe only the price, but a good thickness gauge is expensive.
