reviews

This FilmCube is sick! This thing is amazing! It really helped us on the shoot. I'm gonna need like 3 of them, honestly. Beasty!

FilmCube has made it so easy to rig all of my needed gear to my FX3 and A7siii. I got 2 of them and they fit my workflow perfectly. Finally my camera isn't front heavy or have that terrible gap.

I absolutely love my FilmCube! The versatility it added to my FX30 rig is a game changer and with an affordable price! On top of that; whenever I had a problem with my order customer service took care of my problem within mins! I would definitely recommend the FilmCube!
