Broken equipment, but helpful people
Both of the light stands that came with the Profoto B1 Kit were broken. One of the stands was missing the screw that secures the legs into place, and the same screw on the other stand was bent so badly it wouldn't work. Luckily our shoot location was close to CSI and they let us switch the stands out for some better ones.
Also one of the medium strip softboxes had a hole in it where the wire part goes (so it was sticking out at the front of the softbox). I didn't notice this until we had already switched out the stands.
If you rent from here make sure your equipment looks good before taking it!
Also, I'm not sure if this is a problem with the equipment itself, but the B1 heads were going through batteries ridiculously fast. I was having to switch batteries ~every 10 minutes. Again, this may have nothing to do with CSI.
Customer service was helpful and easy to deal with.
