Typical Park tool quality and thoughtful design.
This chain wear indicator is more accurate than the two point design as it eliminates roller wear from the measurement showing actual stretch (pin wear). This is the measurement that is important.

Great design and simple to use.
Easy way to see chain wear if the end point slips into the chain linkage. Keep your chain clean and lubricated and it will last much longer. An overly oily chain attracts dust and forms a paste that wears out your chain faster and will cost you money to replace.
