I'm very happy with my OctoPod buckle. It is my second one. I like NATO straps, but I don't like putting them on and off and this is where the OctoPod buckle shines. Opening and closing the strap is absolutely effortless. I would also say that the buckle nicely complements the overall design of a watch on the strap. The buckle itself is well made and feels robust, i.e., nothing is loose or visibly weak. The finishing is also very nice and suits higher-end watches. The buckle also holds the strap well without allowing it to become loose and the opening and closing mechanism feels secure and is easy to use. My only small and quite personal complaint is that the overall lenght of the buckle is on the limit of what I can wear with my small 16 cm (~6.3") wrists in cold weather (as can be seen on photos). But it's still ok and the functionality and looks outweight this downside.
