### ⭐⭐⭐⭐⭐ Satisfied customer
*by C***É on June 14, 2025*

Functional, sturdy, and easy to assemble. This was a much needed addition to my lighting setup. It’s the perfect equipment for the job. It’s not exactly light, but it’s well worth the money.

### ⭐⭐⭐⭐⭐ great product

i havent had a chance to mount any lights and modifier on it yet but it feels very well made and all the knobs and screws/thread seem clean and without burrs so everything should work very smoothly

### ⭐⭐⭐⭐⭐ A Great Edition to my Lighting Kit
*by G***. on October 24, 2024*

I use lanterns a lot when lighting doco's. This boom is solid and has a ton of adjustment. perfect for getting a pattern overhead. It's so good I might have to buy another one.
