I've gone out shooting birds with it a few times now, and I must say it's better than I expected when I ordered it.

It's smooth and easy to adjust the balance of your lens on it, and there's a fair bit of leeway when balancing(will hold it's position very well, just got to not fully loosen the knobs). And I was worried my telephoto lens would be awkward, but it doesn't seem to need rebalancing unless you go all the way in to out(or the like).

For video... Eh, I might just have not gotten the hang of it yet. I think you could get decent videos in a pinch, but might want to look at a pan/tilt head specifically for that. But if you're mainly doing stills, I think it's good enough for important moments(much better than a ball head at any rate).

It is big, but it kind of has to be, and it's sturdy which also means it's rather heavy(but not ridiculously so). The worst thing is it being a bit awkward to attach to a bag(keeps bonking me on the head lol), so you might want to keep that in mind. Could always remove the head, but if you're shooting on the fly, that's kind of not an option. Probably depends on your bag, though; I have quite a small day pack I use for hiking around and it's not so bad - just have to be aware of it sticking out.

Would definitely recommend it
