Review on TSA Luggage Locks 4Pack Combination by Jose Strong

I bought these TSA approved combination locks to lock my gun case. When I reinstalled the combo following the instructions that came with it, it just worked. But at some point while turning the locking pin (to reset the combination) it felt like I was pressing the pin and doing something wrong. But the combo resets, so I must have done it right. The worst thing is that the numbers are simply pressed into the surface with no contrasting color. So the numbers are the hardest to read.
