The products appear to work well but have not yet been able to use them in the field. The legs are not screwed at the bottom and do not carry MOZA. It looks like the base has been ripped out because the legs can hardly be screwed in, so it's not secure enough. The screw could be longer. This happened 5 minutes after opening the box. The seller will not replace (exchange) the product, but will accept the return. So I have to return this one, wait for my money and then buy another one. I know Amazon is good for this, so I'm ordering another one on my card to get it quicker, but that's a major inconvenience for a $600 item. This giml gets a lot of praise, so I'll try another one.
