Just thought I'd give an update and put it in this are so others can weigh in on their results.

It's been just over 2 years 1 month since installing Martin's angle drive. I currently have 23,205.2 miles logged onto the unit with no problems. It has beaten the last 2, and it's on pace to beat the best DMCH drive I have owned. And hopefully it will go on to out last the original 2 units I have used on my car too.

If you need an angle drive I recommend Martin's. It may be more expensive, but you won't be changing it as often. At least that is my experience so far.
