Hi jase what video's have you watched?
Was it Jason Lanier by any chance?
I brought a neo of the back of watching Jason lanier's video I very quickly realised that these haven't got anywhere enough power in daylight unless you have the light almost on the models nose.
I covered a wedding last November and I found it very useful for the detail shots but that's a lot of money to spend just for limited use.
I've yet to get out and give it a try in low light using a model, I keep meaning to but just haven't the time hopefully I'll be able to soon.
Probably not very helpful but thought I would just say.
