I've owned this B1 since new (2013). Works perfectly. It took a fall off a countertop a few years ago and cracked the case at the handle. I attempted a repair with epoxy, but it didn't hold very well. I usually shoot with the light on a stand, so it's not that crucial to me. If I do hand-hold, I prefer to use the stand pivot joint.
It's a VERY sturdy light with a ton of power. Lots of accessories out there for the Profoto mount (snoots, soft boxes, filter holders, etc.). Has an internal umbrella mount. Modeling light can be connected to strobe power level or adjusted separately. Beep on/off, sync on/off. Slave sensor and sync port. USB port for firmware updates. Very quiet cooling fan (usually comes on when using the modeling light).
Can use the Air triggers from Profoto (both TTL and "dumb" manual triggers). There are some third-party triggers out there for Canon/Nikon/Sony that allegedly work with the Profoto Air line of lights (2.4gHz), but I haven't used them.
Includes a (non-Profoto) aluminum zoom reflector in excellent condition. Just selling the light and reflector. No battery, no charger, no trigger.
