Review on First Alert ADK 12 Adapter Hardwire by Dang Reid

With this item you can replace a Kidde with a First Alarm/BRK smoke detector very quickly and easily. However, for what it is (wire, with 2 plastic plugs) it is grossly overpriced. The cost per unit would be acceptable here if you could buy them in smaller quantities (e.g. 3 or 6 pieces). . Unfortunately, I unexpectedly discovered that one of those three alarm clocks was not wired or connected to each other. I'm leaving 10 of these to myself, which I hope to be able to resell. . .
