DIYAutoTune Smart Coils IGN-1A Failure

Has anyone had problems with DIYAutoTune Smart Coils IGN-1A? I have had two fail in two weeks. Is that common to have multiple failures? They are only 3 years old.

Very specific guidance WRT duty cycle on those coils (40% IIRC). Depending on rev limit, dwell, wasted spark... this is an achievable number.
