The first actual banger style nail designed for use with electric heaters.
The DDB is such an old design that the 'Deep Dish Banger' (which had to be larger to accomodate the heater mounting) was about twice the size of an average dish.
We revisited the design this past year, and it's really really good. The overall thermodynamics of this 16mm split dish are about the most even heating of any quartz nails. Everything is precisely designed for easy use, full support, and high performance.
The extension below the flat portion of the dish allows the heater to center its energy at and below the actual dish instead of the walls. Simply slide the coil on, lift above the support arm, turn and lower to lock in place.
This isn't the nail for giant dabs, but for the average person's purposes, this style of nail is a staff recommendation among all quartz options.
