Works as it’s supposed to, if it doesn’t drop in the chain the chain is still good Probably 30% longer than a different brand chain checker tool I have. I bought this because my other one only checks to .75 and 1.00. That other one works well for single, 6, 7, 8, or 9 speed chains but on newer 10 and 11 speed chains the specification to replace them is .50 of chain wear. This Park Tool CC-3.2 chain checker tests to both .75 and .50 which will cover multi-speed bikes but not necessarily single speed chains… I mean, you can still replace single speed chains early at .75…

Fast (done in 15 seconds or less), accurate and…
Handy and Accurate Gauge My Trek hybrid only has 600 miles on it and I am planning a short tour (5 days/200 miles) in October. I knew I needed a spare chain for the ride and I ordered one at the same time as I got this tool. I got this little simple Park Tool gauge in yesterday which I got for a lifetime of biking as I always needed one. I previously used the eyeball/measuring method which does work but this tool is very accurate and gives one a ‘feel’ for the chain with the dual measurements that it provides…
