Here's a short review of the boom kit from Lumopro LP682, sold by Midwest Photo Exchange under the reference LUM5120.
First impression, it's an heavy weight good quality kit.
It's composed of
a tripod stand with (removable) casters that can extend up from 4 to 7 ft,
an 8ft boom arm in two sections, with a head that allow to mount stud two ways,
a 5 kg counterweight,
a mounting head.
After some use here are my comments:
the 5 kg counterweight is not heavy enough if you mount a strobe head at the end of the arm. I had to add some additional weight to counterbalance it properly.
The mounting head is too tight around the boom arm and make slide adjustments not smooth (but it will probably get better after some worn out).
great quality at a really affordable price ($124.99).
