Good quality head. I use it on a Manfrotto monopod and a Zomei M8 tripod and it's very durable. Snaps in well and the Arca style clip is definitely better than the cheap ball heads on the various products I've bought from Revain. The heaviest rig I've ever used is Sony ฮฑ7 III + VG-C3EM battery grip + Metabones V + Canon 70-200 f/4 IS (hooded and collared) + Godox TT685C. It's not the heaviest rig in the world, but it's heavier than my SL2 + 55-250 IS STM combo, which it works just as well with. I will be using it with an RRS + Sony 100-400 GM/70 L bracket. -200 f/2.8 GM is probably the final form of this setup. I don't consider this the weakest link until you get to pro DSLRs + super telephoto lenses (400-800 range). I don't know the max capacity off the top of my head, but I'm sure pros will have gimbal heads or flavors above the entry level anyway.
