I bought two SBE2 for my sons. One has had the dreaded click three times while the other has never had one, so far. I bought a SBE3 for my daughter in law for her graduation from medical school. She loves it and uses it for everything. So far, so good but it has only had a few thousand rounds through it.

There are good and bad examples in every thing. My father had a set of Goodyear OEM tire on a new Chevy which he got 95,000 miles out of. When he went to buy a new set of Goodyears they tried to talk him into a better grade if tires to get longer life. When he pointed out that they were the factory tires and had 95,000 miles with tread still remaining they were amazed. His second set had 80,000 miles on them when he got rid of the tires. I struggle
To get 40,000 miles out of any Goodyear tire. Good and bad.
