I think it is great and a lot more accurate than calipers for doing up/down travel matching between shocks. However for myself I have not had great success with using the tool when comparing say one shock with 30/56 and another shock with 25/57 to see/learn what's different. I already know what all the shock changes do well enough. There are a number of people that do and have success with the tool for rebound and shock changes that they are making.
