You get what you expect from a Park Tool
Consistent with previous Park Tool purchases the build material and quality are immediately obvious. The tool, fit for purpose with little assembly was ready for use quickly. Only criticism i would have are the included instructions, however Park Tools online video resources exceed the instructions. There are less expensive copy's available from amazon, but if you want shop level quality and accuracy, look no further.

Park derailleur hangar alignment tool
Built like a park tool, tested on my mountain bike and found it off a few degrees or about 1/4” when checked at the rims. It shifted ok but shifted even better when straightened 👍👍
