I love them as is. About 6 months ago I purchased 10 from Tower Hobbies. I did not like the price they quoted me and told them that I wanted the bulk price I was once given for servos in a bag that consisted of servos with no mounting hardware but with the arm selections. Bulk was not available but she gave them to me at $10.00 each. I never repair them and they seem to last forever. They are all hard mounted on my SPAD planes (I do not use the rubber mounts) with 3 drops of CA glue and a single plastic tie-wrap. I have about 30 of them. I keep enough extra ones so that I can discard one if there is a risk involved. Takes only a few minutes.
