I have one, a DR-630. It is copied from the Domke F-2 design.
If you are expecting Billingham quality at low price, then look elsewhere.
If you are expecting a cheaper alternative to a Domke, then the Dollice works.
It isn't a Domke, but it isn't bad at all. Some black powder came off inside a pocket, but that is a minor thing.
I like it and it is very robust, very good straps.
