"They need a long interval of at least 15 minutes to keep a decent service life. They will last longer the less they are switched. It is possible that periodically, especially as they become dirty, that they will run backwards. It is not ideal but within limits, it is possible."

the first time i plugged my nanostreams in, one ran backwards. unplugged it...plugged it back in, no problems. i've shut them down only once since then, and both needed a few restarts to run correctly.
