Isn't it about the same size as the regular controller but is more customizable. Not sure what else was expected but if they could get better battery life the normal controller would have better life too. That's why I keep my Xbox Elite V1 controller that I can just put some Eneloops in. People mocked that for having AA batteries but I have like 6 pairs of Eneloops and when the batteries get low I can just swap them out easily. Also won't have to break that controller open in several years when the battery holds less of a charge to replace them.
