I have never heard a report of one failing in use absent other forces such as lightning or "serious smoke." W2VJN has written about testing these relays at high SWR and more than maximum legal power for extended period, so why not relax and enjoy a bargain for a change.

Trudging several hundred feet, through 3 ft of snow during a Maine
winter, to futz with a recalcitrant relay at the base of the antenna
will make one wish he had spent a few extra bucks for the vacuum
Remember the USS Liberty (AGTR-5)
