Money well spent! Get it.
Highly recommend this tool for anyone who rides a lot and wants to make quick check and adjustments to their chain tension. Its quick and easy to use. Calibrating it was a breeze. It is extremely well-made and comes in a nice foam padded box with cutouts to hold everything in place as well as a small travel bag. I had a cheaper chinese version of this before and it was trash. This one is worth every penny.

Chain checker
Originally when I bought it I thought it helps adjust the chain. It’s a good chain checker. When you have the chain set up right. It’s a quick way to measure the settings is still the same. Durable I don’t think this thing will break bc it’s solid. It’s good to have around just in case you need to make sure your chain is tight enough.

Easy Chain Tension Tool
Easy to calibrate and easy to use (that knob is a perfect touch). Appears well built and hopefully lasts for many years. I’m not sure how often you should check the calibration but it should last a year before I need to check it again with the factory Ducati chain tension bar. Be sure to check for chain alignment after, as this tool does not check for alignment. Takes the guessing game of perfectly lining the rivets between the small factory lines. Now I can also tension the chain while the bike is up on the stand. Nice purchase so far.

LOVE the ease of this in checking chain slack
Quality, great value for the money, durable construction, and easy to calibrate and use before each ride. I can literally check my chain slack in less than two minutes and know I am good to go. GREAT INVESTMENT and tool for ANY rider with a classic chain and sprocket drive system.

The test of time
This looks like a promising tool. I've calibrated it to my personal chain slack setting but only time will prove if this tool is worth the cost. Just calibrating it in the first few days of ownership doesn't mean it's a great tool. I'll be doing a YouTube video after a couple of chain slack maintenance intervals and I'll have a more in-depth review be it positive or negative.

It Works!
Makes checking the chain a No Brainer. Had the chain set to manufacturer specs for KTM 1290 Super Adventure S. Put this on. Calibrated it. Now tool does the work. Fast shipper and fair price!

Once you set it to your bike it only takes a second to check your chain tension. It is so convenient and really helps keep every thing tight and in place when you are setting your tension no guessing just watch the guage as you tighten and your dun. I highly recommend this tool.

Awesome tool for my KTM890, once you calibrate it and works great, iIonly wish it could have multiple settings for more than 1 bike.

Es practico ya que es fácil teóricamente ajustar la cadena. Seguí todas las instrucciones para calibrar el dispositivo pero no me dio mucha confianza al momento de ajustar la aguja marcadora ya que varias veces al montar el dispositivo en la cadena se movía, lo apreté lo mas que pude paro no queda realmente fijo
