The only issue we ever ran into with a Versaplanetary was when we sheared the sun gear on a 10:1 stage of a 300:1 gearbox. In retrospect it was our fault for assembling it the way we did (we should have had the 3:1 at the output shaft and not the 10:1), and after making the necessary corrections we never had any issues with it again.

Even in the rare instances of failures though VP gearboxes are extremely easy to replace stages on. The exception being in our case due to the way we mounted ours making it difficult to take apart (which, incidentally, would not have been an issue at all with the new v2 VP gearboxes).
