The NT50AE2 is an 18 gauge pneumatic brad nailer that accepts nails from 5/8 up to 2 inches. A selective actuation switch lets you choose between single-shot contact firing and sequential firing, and the depth of drive is adjustable.
Selective actuation is a safety and accuracy feature, because sequential firing needs the nose pressed and then the trigger pulled, so it will not fire when bumped. Contact mode is faster when you move along a baseboard. Because the tool has no motor or battery, it is light and well balanced, and a pneumatic tool lasts for decades with basic care. Compared with the Makita AF506, it is a little heavier but more adjustable.
You need an air compressor and hose, which adds cost and setup. A small pancake compressor is enough for a brad nailer, since it uses little air per shot. Add a drop of tool oil at the inlet if the manual calls for it. Set the regulator around 80 PSI to start and raise it only until the head sits flush. A hose with a quick-connect fitting speeds up moving between rooms.
