How is the accuracy? I have 11 speed 105 and 12 speed gx eagle. I have 3100km on my road bike chain and it barely shows any wear at all. Or maybe I should splurge on park tool one?

considering how most chain checkers aren’t accurate consider this

when buying a new one
Yea, I have one of those. Replace it once it halfway the stalk. DOnt wear out a chain as you start wearing out your cassette soon after.
This is a place to get the right tool. Realize the park tool cc-4 is about $20.
It can save you a $400 rear cassette.
Absolute no brainer.
You will buy one chain checker in your life if you keep yourself together. Buy one from Pedro’s or Park Tool.
You can always just use a ruler or measuring tape.
Use a set of precision calipers so you have a tool that’s good at not just one thing.
new chain = 5.715 in.
1/2% stretch (equivalent to 1/16 in. over 12 in.) = 5.745 in.
3/4% stretch (equivalent to 3/32 in. over 12 in.) = 5.760 in.
1% stretch (equivalent to 1/8 in. over 12 in.) = 5.775 in.
Yes, I’ve used the Shimano one.
Most accurate way: if your chain has a quick link remove the chain, pin it out straight on a piece of wood and measure the full length of it. Each link should be 1/2″ so you can easily see over the full length how much it has stretched against the tape measure.
