Can't comment on durability, but the DTs are way easy to service. Just did mine for the first time. No special tools needed. The most difficult part is just getting the end cap popped off. I think the star ratchets are relatively inexpensive to replace if they start to wear. You do need to be careful to put only a light coating of the special DT grease on the ratchets otherwise they might not engage.

For what its worth, I'm grateful not to have 'angry bee' noise. Not sure what the attraction is.
