This is a convenient 3-light set of mobile studio strobes. The set includes light stands, lightboxes, color filters, etc., and comes with a caster bag. While it hasn't been used much, I recently tested it by taking photos of people, and it worked perfectly with no issues. I was able to obtain the special batteries for the wireless remote. Please note that it's a bit old, and there is some stickiness on the soft lightboxes, some dirt on the caster bag (cloth), and one side of the zipper is broken.

By setting up the camera's transmitter, connecting it to the sync terminal, and connecting the receiver to the strobe, the strobe will fire wirelessly. The transmitter's batteries are special, but I purchased new ones, and the test was successful.
