New adjustable orifice cap available for Jacobus Maid o Mist vents

BroadwichCT

There's a banner on the steam vents page of Maid o Mist advertising a new adjustable cap design that fits existing MoM vents, eliminating the need to swap orifices.  It states that it's even available to purchase separately. Anyone seen one in action?

That's cool, but honestly the orifices do not make much "clutter" being the size of a pea, and are dirt cheap, dead simple, and 100% reliable. I might get one just to mess with but if I were a tradesman I wouldn't bother.
