Used PocketWizard MiniTT1 Flash Transmitter -Nikon

The battery compartment is snug, which I like, and the 100-day warranty gives peace of mind for a used buy. It paired instantly with my speedlight, no hiccups so far.

Picked this up used and it's working flawlessly with my Nikon speedlights—syncs instantly with zero lag. The battery compartment is snug and the included battery lasted through a full portrait session without dying.

Shot a full engagement session outdoors and the remote range was rock solid, even through a brick wall. The battery compartment feels snug, which gives me confidence it won't jostle loose during a fast-paced shoot.
