In 2012 the supershifters cost us a regional. There was a problem with roll pins shearing that year (we found out later). At the end of the last qual match (which we won), the pin sheared. We did not know it until one side of the drive would not work during the first semifinal match (we lost). After the match, we looked it over and couldn't find a problem. In the second match it still wouldn't drive (we lost again). Turned out unless there was a load on the drive it did fine, but as soon as we loaded it up, it would start to slip.

They may have corrected the issue since then, but be aware.
