They do work, and work just fine overall. I bought my brass ones at B3, and was surprised to see 'Rain Bird' (the lawn watering equipment mfr) on the package. I later bought one of my sets at the local Ace to save a trip to Concord. And you do need the garden hose thread-to-1/2" NPT adapters, but the local Ace carries those as well here, so HD may.
As mentioned, the rubber gaskets don't hold up forever- I have to replace them every year or so, but the upside is that a 10 pack is less than 2 bucks at Ace.
