I use these strips for testing in the 3.5-5 range. We can tell if something is much higher or much lower, but it's really difficult for us (us, 3 pairs of eyes, 21-63 years old) to differentiate between stick to chart matches in this area. But at least we know we're in the ballpark, and at least testing the bars below 5 (theoretically). Very easy to use.
