Yes, they are good enough. The thing is, prove it for yourself. Put a feeler gauge under one, and see what it says. Then try a few more. If you aren't happy they will take it back, and it is only fifteen bucks anyway.
I am a scientist, not an engineer. We get numbers from instruments costing a million bucks. They vary from sample to sample, and even running the same sample more than once. So keep in mind that any time you measure something the accuracy and precision of the instrument are only some of the limitations. Averaging can be very important, and even more important are chasing down sources of error and variation, such as how do you attach the indicator in the first place.
