As for the product, I find the great contrast to one and bad advice in writing this review.
1 - For the solidity = no problem.
2 - For the holding of flash = there is no provision for its lock. Over time, the plastic support takes the game ... If you forget your user to lock flash 460ex or 580EX (or other): beware it may slip when the ball is very slanted and falling ...
3 - For the fixation on one foot = no problem. I opted for the attachment on walimex Quick plates.
4 - For tightening screw = no problem. It is very powerful, both for the ball as for holding the umbrella, so that they leave a mark to each of my settings.
5 - In summary = I do not just serve this ball for me always put an umbrella. However, every time I use it, there is always a flash. So a screw or screw system for the Lock the flash is not too much!
I have two of these products for more than six months and I am satisfied.
