I have yet to get enough data that is comparable. I am finding that its ability to provide actual timing is helpful - especially if you have several motors of the same brand that you want to get in the same ballpark.
The unit can be an asset for a motor head that already has experience in using rotor strength meter, inductance meters for stators and a load-based dyno.
Totally user friendly but it is to early to get good understanding of how to use the data to evaluate a motors performance.
Worth the money?
I would start with tools that measure stators and rotors first.
As a motor guru shared - nothing beats a solid stator. Finding strong rotors is a plus.
Then, some version of a load based dyno (a little bit of work but it is the Competition Electronics Dyno converted to test B/L motors) to see how the stator + rotor work together.
The Motolyser is a good tool. Hopefully will become more feature rich once more R&D kick in. It is valuable that the unit can be updated by the user.
I think a detailed Motolyser 101 from Jim Dieter would help pros/cons.
