it seems like a good library to me. It's true though that the api is quite different from that of redux, but I guess that must have been the aim i.e to make the usage simpler while using redux's power under the hood.
I can't speak for anyone else, but I find that tools that wrap Redux into something that is inherently different than, you know Redux, tend to be disliked. At a point, there's very little point in even acknowledging Redux, other than as a child dependency.
