Charlie - I know of only two actual failures in use -- the first led to the Halcyon/EE recall; the second was a failure of the same type of knob on a Diver's Supply/Sea Elite manifold which was recently reported on the Florida Techdiver list. The underlying problem is that the "fake" Sherwood-style knobs preinstalled on recent manifolds supplied to both Halcyon and Divers Supply are defectively designed. Only a thin metal disk molded into the knob engages the valve stem instead of the large brass insert in the genuine Sherwood knobs. Once the disk rips free -- and it's likely to over time -- you won't be able to turn the valve. Is it an imminent safety hazard? Probably not since the knobs are most likely going to fail when you turn them hard to a stop -- either all the way off or all the way on -- but DIR is all about eliminating unnecessary risks and a knob on the verge of failing completely could prevent you from isolating a valve in an emergency. Even if not life-threatening, a manifold failure could certainly ruin a good day of diving. Only Halcyon has stepped up to the plate and issued a recall, but since real Sherwood knobs and washers are only a few dollars and take seconds to install, there's no reason to take the risk with any of the manifolds. BTW, I happen to have a Sea Elite manifold with the knock-off Sherwood knobs, so I've had a chance to take a close look at them. I'll be replacing them this weekend!
