T type chain checker from Park.
Correct chain gauge for checking SRAM T-type flat top chains.Gets plenty of use and no signs of wear.Not cheap for what it is but regularly monitoring your chain wear will save you money in the long run.

Park Tool quality
Simple , accurate and effective for 12 speed SRAM chain. Good quality like all Park Tool kit
User
High quality make
The tool is high quality make and seems to be very accurate. However, it's a bit pricey.
User
Expensive but accurate
Expensive but park tools can be trusted to be accurate in the machining profile of the tool unlike the cheaper options
User
Easy to use and goes to 0.5 wear
Good quality chain wear indicator, as to be expected from Park. Easy to use and measures down to 0.5 wear, when most others on the market start at 0.75, by which point your chain is already too worn for most 11+ speed setups...which most bikes are these days.

Does the job for SRAM Eagle 12 speed
Perfect for measuring the chain on a SRAM Eagle 12 speed setup, as it's park tool, it can be trusted for it's accurancy, which in turn should lead to more life out of cassettes and chainrings.

Great quality chain checker
The tool is well made and durable (sturdy sheet metal). It has the instructions to use printed on the tool itself, so it's not hard to use. Checking the chain wear helps prevent wear to other parts of the drivetrain, so it's important to have one if you don't want to end up replacing your cassette and chainrings. It's on the pricier side, like most Park tools, but you definitely get what you pay for.
User
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.

Simple, Accurate and Easy to Use
Pros:✔️ Very easy to use✔️ Longer measuring span reduces error✔️ Solid and precise build✔️ Quick chain check in secondsCons:✖️ No real drawbacks for this type of toolReview:It simply does what it’s supposed to do. The tool is straightforward and very easy to use — you can check chain wear within seconds.A big advantage is its length. Because it measures over a longer section of the chain, it minimizes measurement error compared to shorter gauges. This gives more confidence in the result, especially when maintaining drivetrain components regularly.Overall, a simple but essential tool that works exactly as expected.
User
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.
