engine torque damper

Hey guys,
Don't know if anyone has been able to compare brand to brand, but apparently ingalls do a good engine torque damper but i was just wondering if anyone has had experience with a tegiwa ETD. There slightly less money wise but no one seems to have a review on one. Any one tried it out?
Cheers
