So these belts will tend to last longer than traditional belts but eventually they will degrade. Thus if you change them early enough then this isn't going to be an issue, generally from what I see if you drive your car alot then heat cycling (makes the belt hard) and mileage will be a bigger factor than cracking from ozone (which is a problem for cars that sit alot like summer cars).

But in response to your question I have no idea how each manufacture makes their belts in terms of their resilency to ozone, I do notice that belt technology have gotten really good as of late.

FWIW, it looks like ECS has switched over to the Gates belt wear tester: https://www.ecstuning.com/b-gates-pa...esweartool~ga/.

Both it and the ContiTech units are apparently for professional mechanics, as they're impossible to find online (except for the Gates unit at ECS).
