Pretty good for the price
It does what it is supposed to do, but it is not a high quality tool, not that I expected it to be.

Gets the job done
1 of 1 found this helpful This is a quality tool that does just one job, but does it well. I was amazed how out of alignment my mountain bike's derailleur hanger was until I checked it with this tool. After correcting the alignment, the annoyingly slow shifts and "clacking" noises that occur in certain gears are gone. My only gripe is that there is a certain amount of play in the head unit that screws into the derailleur hanger. The play is amplified at the end of the arm where measurements are made. Even so, the alignment was so improved with the tool, I don't think the amount of play present has any significant affect on the results.

Careful that you have the right crank for it
My bike was spec'ed with SRAM Eagle Gx carbon cranks. This is OEM only and is not available aftermarket. I assumed the crank arm would be similar to Eagle X0 and XX but it must be slightly different. The boots fit but it causes them to pucker slightly and the hole on the back side does not line up well with the pedal axle. It is very difficult to get a hex key through the hole in the boot and into the hex socket on the pedal axle. Water and mud accumulate in the pucker created by the poor fit. It appears to be a good product, just be sure you have the right crankarm before ordering it.
