CAMTREESwing Away Wide-Angle Sunshade Matte Box for 15mm Rod. For Lenses up to 105mm in Dia., Tool-less Operations. Two 4x4 Filter Holders & Fabric Knicker. Complete Protection from Flares (C-MB-20)

I do like the price point but the quality is mediocre in my opinion. I found the 15mm rods were tough to slide on and off even if you loosened the nuts. The swing arm is alright but a bit clunky . The frame holding the filter is pretty cheap plastic so if you dropped it I would think it would break. For day to day use I think this would wear out pretty quickly. The MB 23 CF version is noticeably better but more expensive and it has the same cheap filter holder.

Shoddy build, doesn't attach well with all rails, barely any space to maneuver with. The 4x4 holders are okay.

The quality of material is very nice. This works great with my Rokinon cinema lenses and smallrig with C100mkii

Professionally built to handle most cinema lenses.

Very nice matte box. Everything works great on it. I will probably be buying another one for my other rig.
