The Park Tool CC-3.2 Chain Wear Indicator is a useful tool that allows you to find out how worn your chain is before you need to change it. A worn chain not only shifts poorly and wears down sprockets at an accelerated rate, but it also causes damage to other components of the drive chain. To use the CC-3.2 Chain Wear Indicator, simply insert the tool into the top of the chain and read the measurement. If the chain reaches between 0.75% and 0.5% then the chain is worn or beginning to reach its end and needs to be replaced before other chain components are affected too. - R.K.
Please Note: Consider that if you replace a chain because of wear other vital drive-chain components may need to be renewed too.

I had a slightly noisy drivetrain on one of my bikes but I didn't think had a great many miles on this chain and cassette. A quick check with this simple tool confirmed that it is worn past 0.5% (but not yet past 0.75%) so I've happily ordered new parts. No more guessing!
I bought this to monitor my chain wear and to keep the shop mechanics honest. Great little tool that is easy to use. Well made and at a little over $12 great value, even though it is very basic. I have 3 bikes and I use it regularly to check chain length. Good investment I think.
You need one of these to ensure your not preternaturally wearing out your components.
Also PBK gave me the newer model which measures .5/.75 which is better because you buy a new chain at .5 then replace your chain at .75
Saves you money in the long run by letting you know when to replace your chain, reducing your component wear.
