Basic info:
For 1 - 10 speed chain, use .75 and 1.0 tool.
For above 10 speed chains use a different tool: .5 and .75.

Can also use a ruler to measure from the middle of a link to the middle of the link at 12 inches. For a 10 speed or lower, if stretched longer than 1/8 inch then consider replacing chain.

Very simple to use and accurate. I had a worn out chain, and replaced it. Bicycle (Giant Sedona 3X7 gears) shifts much better with a new chain.

The chain stretch tool looks good and the guides are marked and was used to confirm state of chain.

Pretty simple gadget, not much to go wrong. It's metal, sturdy.

Does what is it supposed to do.

Works great!

I did not need this tool to tell me if my chain is worn out.

These people also make bike chains. Strong bike chains. Anyone that's put a few miles on an e-bike knows how critical chain awareness is. This is a great tool that is accurate.

Product probably works fine but the item description is poor. This product WILL NOT work with 11 and 12 speed road bike chains which is not mentioned in the description.

This tool is smaller than others around.
It's made with very good quality and it should last you many years since this tool does not wear down. This was tested on a known worn chain.

Pros -

-Easy to use, seen the worn chain right away
-Compact size fits in your pocket
-Nice black Finish.

Cons-

None, this tool should easily last for years since the wear on it is minimal

Excellent, great quality
